TL;DR
It would be nice if you could see if a filter inserter has a white or blacklist when having ALT mode activated.What ?
Currently you can see the contents of a filter when having ALT-mode activated, but you don't know if it's a white or a blacklist.It would be nice if there was a visual difference between a white and a blacklist. Not sure how exactly that would look like, maybe a green and red tint?
