When right-clicking on an window in the task manager widget, the context menu contains an entry "Configure Task Manager" right above "Pin". I think it doesnt belong there as it is actually unrelated to the window/app, in contrary to the other entries (which you would expect from a _context_ menu). Furthermore I believe that the wish/need to, to actually configure the task manager is quite more seldom than the other tasks in that menu. Hence this entry is adding unnecessary bloat to this menu. Instead the task manager can be configured by right-clicking on an empty space in it or via krunner (I believe, cannot check right now). I'm posting this bug because I have the feeling that the context menu contains to many actions, which is overwhelming and IMHO a disservice to the user. Instead we should try to focus on the task the user actually wants to perform.
If we did this, then there would be no way to access the configure menu item when the Task Manager is full, unless you deliberately go to Panel Edit mode. It's already a challenge to get people to realize that widgets are configurable, and I fear that this would only worsen the situation. I do hear your criticism though, and I think it might make sense to hide it a bit more in a sub-menu with the Alternatives... item. I can look into that.
It cannot be configured via runner, but it can be configured when in "configure panel" mode - even when the task bar is full. This seems cumbersome, but this is _only_ needed in the case you want to configure the task bar when it is full. IMHO justified...
Git commit 1daf42d9d734f969c31016825d8a7a93a6f95fbb by Nate Graham. Committed on 13/03/2019 at 20:54. Pushed by ngraham into branch 'master'. [Task Manager] Reorganize and improve presentation of context menu Summary: This patch improves the UX of the Task Manager's context menu by offering more logical separation and grouping of elements, improving strings, and adding or changing icons, as appropriate. The result hopefully feels more harmonious, less confusing, and less intimidating.
