SUMMARY After the re-write of the users KCM it seems to only use one column, no matter how big the screen is. Visually that looks a bit awkward and from a usability point of view you lose the ability to quickly change between users. Currently one is presented with a list of users. When selecting one, a new section opens and the list is hidden. I think a solution like before where the list of users stays visible also after selecting a user would be preferable. This might also be some Meta wish, since other KCMs might behave the same and it is probably worth to check that they all look similar.
