Right now, newly-installed applications aren't specially highlighted anywhere, making it more challenging than optimal for non-technical users to know how to launch them. In Ubuntu Unity, newly-installed applications automatically show up on the always-visible Dock. In Windows, they appear highlighted at the top of the Start Menu. We should consider doing something to highlight or display newly-installed applications more prominently.
Kickoff did have code to highlight new items at some point
(FYI this is a continuation of a conversation started at https://phabricator.kde.org/D7905)
It used to have a "Recently installed" category until it was rewritten to use Kicker's backend.
Great idea, would be really nice if we could implement this!
