It sure does. There is a plan in place to fix this, tracked at https://phabricator.kde.org/T7256 We'll keep tracking it there.
There hasn't been any activity there for almost two years, could you point me to a file where this UI is stored, so maybe I can try to do something about it.

Note that the biggest reason why this hasn't happened already is because it is using an old UI technology. The plan is to port it to QML and then redo the UI in the process, or right afterwards--as we have done with other new-style KCMs that have an improved UI. If you want to hack on the UI now, that's totally fine, of course.
