Improve Kickoff touch interaction and general aesthetics
Improve Kickoff touch interaction by increasing list items and footer items vertical padding. Also de-clutter Kickoff by removing header and footer vertical lines which aren't needed because there's a clear distinction between elements.
These changes made using Kickoff with a touch screen much easier than before without dramatically changing the appearance.
PD: Since I'm not familiar with the coding style used in KDE, please forgive me if I wrote something terribly wrong
