When I split the window into two or more panes (View | Splitting | Split {horizontally, vertically}), it's hard for me to tell which pane the cursor is in. (OK, if jEdit is the only app I'm using, I can probably remember, but when I switch to a different app and then come back, my memory fails me.)

Currently, the only way (AFAIK) is to look for the "caret". But this can be hard to notice, even if it's a blinking red (outline) block. (No comments on my eyesight, please!)

My suggestion: when the current line is highlighted (Global Options, in the dialog box "Highlight current line" is checked under jEdit->Text Area), only highlight the current line of the *active* pane (= active "Text Area").

An alternative or additional possibility would be to slightly gray the non-active pane.
