Feat Request: Always outline active frame

Is there a feature that always outlines the active frame, similar to the yellow outline when gF is pressed. The reason I am asking this is because it can be annoying to try and focuses a secondary section where you can scroll, or something similar. I have to manually spam gf and then try to scroll to see if I am focused correctly. If this is a feature in another fork like vimium-c or not planned, then please let me know. Thanks for maintaining this project.

Start by locating the existing gF command and the code that draws its yellow frame outline. Trace how the active frame and scrolling focus are tracked, then determine how an outline could remain visible without disrupting frame interaction. Done means the active frame is consistently outlined and focus remains clear while scrolling.
