Another behaviour of icon task manager on clicking grouped icon.

It is possible to set it that clicking on group i task manager will show last active windows from group, not pop up menu?

  • KDE or, GNOME or, something else?

For the case of KDE, the application’s window list is ordered by time – the most recent incarnation of the application is last item in the list …

I use KDE. When i click on icon of grouped apps in task manager I have full screen option to choose window. I don’t want to have that, I want last active Windows to pop out or all of them.

You could browse through KDE’s “Usability & Productivity” project to see if this feature is being implemented: for the 64th week of the project, the report is here: <https://pointieststick.com/2019/03/31/kde-usability-productivity-week-64/&gt;.
There are previous reports available on the right hand side.

If nothing suitable has been considered by the team, you could consider raising a Feature Request by means of a KDE Bug Report: <https://bugs.kde.org/&gt;.
