Version: (using Devel) Installed from: Compiled sources incorrect taskbar entry width when closing BUG that I like, thus kind of WISH. when I open app A I get AAAAAAA in taskbar, I launch B and I get AAAAAAA BBBBBBB I close B and I get AAAAAAAAAAAAAAA Well, a bug -- isn't it? But I would rather opt not to fix it! No kidding, rather make it consistent -- i.e. provide that behaviour from the start. So, the wish is: set minimal width for taskbar entry. Divide whole taskbar width per N (launched) apps, if the size is bigger than minimal use it, if otherwise use minimal. I think it would be great, with three apps there will be more space to click, there will be more space to show the app name and document name, etc.
Current KDE 4.1 seems to be similar to what you describe you would like. One task takes up half the taskbar. Two tasks take up a third of the taskbar each. If I close one of them, the remaining task goes back to taking up half again. If this is not the behaviour you experience with 4.1 final, please reopen.
