Here's a couple of settings that feel missing on the fullscreen Application Dashboard: - how many recent items to show - custom categories (not sure if that's possible, actually; I tried adding a custom category to a .desktop file and it got filled into "Lost & Found") - grid spacing: this is the most important one, as there are only a few characters available for the application names, and even the most basic ones get ellipsed (such as Telegram Desktop or LibreOffice Writer) [related to Bug 365936] - icon sizes?
These seem reasonable for consideration
