Created attachment 124759 [details] Menu of the actions, with the settings of the task manager. SUMMARY Make actions of right click menu on icon tasks, always affect all instaces, if they are grouped together. OBSERVED RESULT When task manager group programs by name, without checked Open groups in popups, cannot close all instances of a program together. When Open groups in popups is checked, all the actions(including more actions subemnu) affect all instances from icon menu. EXPECTED RESULT Ability to close, minimize etc. all instances of a group. KDE Plasma Version: 5.17.4
This already works for me. When I open two instances of an app and right-click on their grouped icon, any of the actions I choose affect all of the instances. Does this not work for you?
I'm pretty sure you use Icons-only Task Manager, which has hidden option "Open groups in popups" enabled. I use the classic Task Manager to enable inline grouping. Notice the multiple icons of dolphin instances. It is not a bug, was never designed to do this.
Ah ok, so for the regular task manager, yeah.
