Hey, and again sorry for late response.
I think this feature would help greatly your software.
Already the fact, that you can now see the window being open on the monitor on which the app was started from the start menu is great. The only thing it lacks are the shortcuts on the 2nd monitor taskbar, and applications run from the explorer window on that monitor(I assume it's harder to do).
I will give an example. If I move to my 2nd monitor, and I have a shortcut on the display fusion taskbar that points to "Desktop" folder, sometimes when I click it, it opens on the 2nd monitor, which is a bit annoying, as if I click the icon on the 2nd monitor, I probably would wish to have it open there in the first place. So ultimately what happens, is that I have to move it manually. A feature, where ALL the shortcut apps/folders that are opened on the display fusion taskbar will be open AUTOMATICALY on that monitor.
The 2nd request, which like I've said is deffinetly much harder to do
, would be to run anything on the monitor that it was run from. I will give an example. If I have a folder(explorer window) opened on the 2nd monitor, if I navigate to say notepad.exe and I double click it, ideally I would like to have the window of notepad open on that 2nd monitor, not on the 1st or any other. Do you know what I mean?
Anyways I'm glad you guys like couple of my ideas, and I hope you will at least think carefully of trying to implement the ones I gave you above. I really think it would be a big step forward in making your software even more perfect.
