especially on multi-monitor setups, it would be great if there was a way to click or work in application windows without having them jump in the foreground and covering up everything (on every monitor).
Fixed z-order for windows (keep z-order if a window is clicked)File manager spanning three monitors that covers up everything else on all monitors every time you quickly want to look something up, or quickly change a folder, scroll position, or similar (click to enlarge)
It would be amazing if someone could think of a way to code an utility that could provide this feature. TXmouse
by Andy Polyakov actually (sort of) does it, however not with all applications (anymore), and with some unwanted side-effects like automatic window activation on mouse hover.
As with TXmouse, if you actually do
want to change the window z-order (and bring a window to the front), you simply click on the respective windws's titlebar.
I've described it in detail over at the Actualtools.com forum, so please bear with me posting a link to the respective discussion:Fixed Z-Order, don't change z-order if a window is clicked
