Quoting "Chengqi(Lars) Song"
I have problem when using gimp. all Gimp's windows are set to be float. But when I open two pictures, the 1st one's window is covered by the 2nd one. And there is no way to switch their Z-order so that the 1st one can be brought to front. Is there any way to always bring the focused window front?
Floating and tiled windows are interleaved in layout order. Layout order determines z-order. Therefore, to change z-order, use whatever keybinding you have for moving windows around within a layout (default mod-shift-j and mod-shift-k); you may have to press it several times to affect the (visible) z-order. Specifically for the Gimp, you may also enjoy the "tab" keybinding that Gimp provides to hide and reveal the auxiliary toolbar dialogs. Cheers, ~d
