When sorting tasks by desktop and not filtering by desktop, it can be very difficult to determine which task is on which desktop, which can make it difficult to figure out which window you want to select. E.g., I have a bunch of pdfs open on various desktops, but since their window names are not memorable (e.g. 2039483.pdf), it would be of immense help to know which desktop their on, because I remember which pdfs I have open on which desktops. One idea would be to have windows assigned to one desktop divided by a separator from those assigned to adjacent desktops. Another would be to assign different background colors to different desktops. Another, which I prefer least, would be to group windows from the same desktop so, e.g., if one has windows open on six different desktops, the task manager will show at most six different entries.
The desktop info should be in the tooltip.
The point is seeing desktop info at a glance, so the tooltip is of no help. (Not mention that I have tooltips disabled.) Strange, I thought I had attached a mockup of the idea... Why "needsinfo"?
I should ask you if the indicator in the tooltip could meet your demand. Cancel it.
