I wish to improve the visibility of the searched elements, I mean while using the search window

I see two possibilities: - Display the yellow arrow in the marker area (as when there are compilation errors) - Activate highlighting of the current line even when the window does not have focus

I would prefer the first solution, for the second I discussed with Lex Trotman in Geany-Users list :

probably the best place for the setting is in

preferences->editor->features since editor->display which is its natural home is a bit full
