Yes. The text block for entries without images is long to fill the space that will be occupied if other entries have images. Or if all entries have enough text it will also look fine of course. A single entry doesn’t take other entries into account though. That would get way too complex.
Haven’t tested it and don’t guarantee it, but auto-posting should also see the Open Graph data when the Facebook crawler looks at the page. So it might work.
Pretty sure this is working as intended, but the error message is maybe a bit misleading. It detects that it is an Instagram link, but since there is no specific post, it won’t do anything with it.
SuperTopics doesn’t care about tags.
I would suggest to test the same block with the stock template vs. the SuperTopics template activated. Does it show up with only with the stock template? That would point to a SuperTopics problem. Does it never show up with tags activated? That would point to a faulty blog setup – or maybe caching problems.
I don’t know. I can look at it in your ACP, but the block filters (in this case event categories) shouldn’t cause any problems. SuperBlocks is just styling. It takes whatever entries the the Pages blocks provide. Does it show if you assign the stock template, not the SuperBlocks template?
One entry will fill the entire width and if there is an image, it will be used as background image over the entire width. That is intentional.
There are image settings in the plugin settings to show more or less images. But you probably don’t want to remove the background image as that is one of the key features why people use this block template over the default one.
No. You can choose from 6 different layouts connected to the number of entries in a block. The layouts itself cannot be changed. But you can add multiple blocks to the same page for more variations.
At the moment, this style is only available for Pages record feeds and Forum posts/topics. Doing it for Blogs is certainly possible, but I am not sure there is enough demand for it to release it as a Marketplace product.
