The functionality of the Activity Stream filter is great, no complaints, but the resulting output wastes a lot of space in my case.  See the attached screenshot.  I request that the area highlighted in yellow be collapsed/hidden by default (or setable as such in settings somewhere).  I think most users set-and-forget and would appreciate less noise on the page in most cases.

@Jon Matcho add this code to your custom css:

body[data-pagemodule="discover"][data-pagecontroller="streams"] .ipsSpacer_bottom[data-role='streamOverview']{ display: none; }

Before:

After:

or if you want to delete a little more, you can try:

body[data-pagemodule="discover"][data-pagecontroller="streams"] .ipsSpacer_bottom{ display: none; }

but I'm not sure if it won't brake something

After:

It's possible it will not work for some themes.
