I just installed Beta 15, great work on the update!
Not sure if anybody has said this before, but the new dashboard isn't an upgrade from the previous one, in my opinion.
I get the idea of trying giving every extension it's own "space" and showing relevant permissions, but now the dashboard looks very messy (especially if you got 20+ extensions in your community). That also doesn't look very scalable, especially since many extensions like BBCode don't have any settings to configure and just take space in the menu.
Separating it into categories: like Basic, Permissions, Appearance, and Extensions made much more sense in my opinion.
The "Search Extensions" functionality is wonderful.
