How to make active pane look different than others?

[lededev]

Also, how do I make the view where the input focus is located visually different from other inactive views? It's a bit difficult to determine which view gets focus right now. For example, I want the activation view to have a horizontal line above the activation tab, or let activation pane's tab bar background color change.

I would install an add-on "Inactive pane".

Thanks for the hint, I'll reference this part of the code to implement an add-on that changes activation pane's tab bar background color. Change all inactive panes background redraw too much area on my layout.

You can tick "Background" option of "Tab plus" add-on to color (grayish blue) the tab bar background of active pane.

Then you can use "User style sheet" add-on to change that grayish blue to another color (e. g. light yellow):

.activecaption {
    background-color: #ffffbb;
}

There is a side effect that all inner tool bars will also be colored, though.

Alternatively you can use the patched version and set background color of file list (and folder tree) of active pane
