I was wondering, if it would be possible or even somehow otherwise achievable to be able to set up a different view mode (ex. coloring ) for the tabs, which have an applied filter.
The point is to have the possibility to set up a corresponding rule... similar to the "S SearchResults" rule for automated switching to the view mode
I would say it is important for cases, when one applies filter (say on extension), but then gets distracted and away from the computer.
When back one might delete "empty" folders which eventually contain encrypted files.
Of course there is no cure for human stupidity, but at least hopefully there is some relief

Regards,
