as someone who uses several (SEVERAL) xterms on the same screen and focus-follow-mouse, my best bet to see where my words will go when i type is to notice which screen has the blinking green cursor instead of the static white one.

that one would help a lot.

(i used to have a very visible window manager active border and shadows, and also lower the opacity of the non-focused ones... but gnome 3 designers in all their wisdom decided i didn't need all that)

I do that with XFCE. Active window gets a bright title bar and borders with dark text, inactive windows get dark title bars with light text and thinner borders. High contrast in both cases, but easy to differentiate.

Themes like that are very easy to change to suit yourself.

I know, i did that on every window manager since Irix.

But gnome3...

I'm only using it because I'm stubborn. And because i maintain one somewhat popular gui app and i want to test it where i know none of other contributors are testing
