I have problem which annoys me beyond recognition
I have workflow in which multiple windows of same program are monitored by script and according to state of the program X window icon is updated to reflect needed action (
set-icon $WINID state.png). For a while it was working quite well, however recently I've updated my box to Kubuntu 16.04 - and this was the worst idea EVER.
It looks that task-manager flag "Use launcher icons" was removed and it's not longer an option to disable this - Plasma forces using launcher icons (always).
Moreover this option seems to be removed completely from config files too.
My question is - is it possible to restore this functionality? To restore older version of task-manager?
Or is there any other way to change (by script) icons of buttons on taskbar?
I've tried to disable plasmashell completely and use some other panel (fbpanel, lxpanel, etc.) but those introduce more mess within KDE than help with the problem
