I'd say so, it works fine for me. I never tried their free version first, though, but I too was going to suggest that maybe having the free version was why your screenshots didn't work.

I use the Screenshot Machine option, and got the Pay as You Go "pack" for €20 which gives you 2000 screenshots, which I've found to be more than enough for me. I store them locally. Once in a while, not often, it doesn't (can't) grab the screenshot, so I upload my own.

Might this app be of use? Except it's "not currently available for purchase." You might want to check the support topic, as there currently seems to be a bug with it if it's set to ignore topics with replies. It's identical to a similar hook that used to exist for IPB 3, I think called Forum Pruner.
 

thanks for the report, I'll try to address the critical issues this weekend.

I did my further investigation and I want to point out some cases and issues to @Fosters ' attention:
a) the activity stream shows a bookmark title (if any provided) rather than an item name (like @MIXOH described in his second point. Just an adding of the line "$containerType = $container::$title;" doesn't help);
b) is it possible to put all the application settings in one place? If a big community has lots of groups, it becomes annoying to change them one by one for activating the bookmarks. Also, for me it was hard to find the place, where you input the "simple mode" activation 🙂 Why not to let all the settings editable in one separate place?
c) when adding a bookmark, we see the bookmark adding time, but there is no time for the message posting, and even no author of the bookmarked content shown! Would you mind implement this please?
d) If the simple mode is activated, the bookmarks are added in the Private status only. How about adding a setting to choose the status of the bookmarks, when they are added in the simple mode?
e) How about letting members choose by themselves, if they want to use simple mode or enhanced mode?
f) if the group setting does not allow that group's members to add private bookmarks, in the simple mode they are still added in the private status 😞 
g) If a group doesn't have an access to the Application "Bookmarks" (no permissions given through the Application settings on the Applications' page here "&controller=applications&do=permissions&id=125&subnode=1"), users in this group are still getting notifications, when their content is being bookmarked (by Public bookmarks)! 😞 I believe, it should not work in this way.
h) Private bookmarks are automatically added to the existing bookmark category, even if I don't choose that category when adding those private bookmarks 😞 That's why now I see 7 bookmarks inside my category, but it shows the number "4" (three of them are private, and I didn't choose that category for them when adding them) here "/bookmarks/bookmark_cat/?category_id=1"
I find your application very useful and important to my community (otherwise I won't purchase it 🙂 ) , but it needs some improvement for sure...

I have this too... It's very confusing as it makes it look like, for instance, that my bookmarks are theirs, when they're not. I see this on my test forum and I've consequently not installed the app on my real forum for this reason 
May I add to the feature requests, please?
- Could we have categories in private bookmarks as well as in public ones?
- Could bookmarks be made editable - so that one can edit a title or change category, and change a bookmark to private or public? If I should decide to use the public option, I can foresee my members making a bookmark public when they meant it to be private, or vice versa.

Hello,
Why my own private bookmarks are shown in other member's profile nodes (tabs)? Is this a normal behavior? If yes, what is the reason to do this? Those users, even with no content at all shouldn't have this tab with the bookmarks, which are no related to them at all. In my opinion, since the bookmarks are private, I should see them only in my own profile tab.

Thanks so much, that's very helpful

Yes in your case 450 is raccomanded, keep in mind that email tests are not counted so it is right to remove some numbers from the maximum allowed (there are no other cases into IPS framework).

I advise you to set up bulk mails with lower priority because they could delay the most priority emails.

This setting work when try to "send a new mail with IPS framework"1 and if MTA (not only smtp method, but anyone you have configured) is offline the email logged as "421 error" are processed when the service return online.
1. the counter increment before send is called, regardless of errors arising within send (\IPS\Email\Outgoing\Exception) because currently I have not found a way to detect if error is temporary or not (only 421 seem to be temporary).
As I specified in the answer above it works with the configured method.

I can confirm the issue on Top Hits widget. Will release a new version as soon as I fix it.
There won't be a "group permission". It will be like all other widgets: if you have permission to view the link, will show up.

Ok, clear now. Just test on my online board (using phone) and I can’t  see a deleted link as a member. I’ll retest tomorrow in the morning when I reach my PC.

Super, thanks, Esther
I used to use this app on IPB 3.3.4 and have recently , albeit belatedly (!), upgraded to 4.3.4. Whilst IPB 4 has tons of options for creating activity streams (which is great), I can't exclude a particular forum (stuffed with RSS feed imports, set to no replies) from "All Activity", so that particular forum tends to swamp "All Activity". Also, my members will be more familiar with your app than with what might be considered by some not-so-forum-savvy people as a rather complicated IPS "Activity" in general.
So I'm off to buy Social Streams now

there is a top spacer division in there, I will remove it in the next update

Updated to 1.0.3
New Widgets & Features
Added another recent post widget showing 3 lines of the users reply Added lots more settings to the topic & post widgets Added translatable language strings to the widget headers Bug Fix
Fixed the bug where it didn't show any posts when selecting to show them from certain forums

You're a multi magical star in that case! Once again, thanks so much!

I will change the bit where it says what forum it is in to the topic title, that will also be a clickable link to the actual post itself

sorted, will be in the next update

OK I have made some changes to them anyway for the update, added lots more of settings to the main widgets as well, these all should be OK from them on
I can maybe look into making another widget what will have that
When I was younger and didn't have kids, I partied hard and would sleep probably about 2 hours a night some nights no sleep just go straight to work from the club I left lol, and even now ( I don't party no where near what I used to ) but I hardly sleep so I actually have a lot more hours in my day then most other people lol

I'll check it out tonight and get back to you

Yes, this app uses data from old version. Upgrade your board then buy this version if you already haven’t made it and upgrade Links Directory. New screenshots will be generated. 
Let me know if you need help after upgrade your board.
