That is a great idea actually! I learned about text filters only when
I decided to fix a minor bug connected to them. A hidden gem indeed.
If no one opposes the idea, maybe someone could make an issue about
this to the issue tracker and then it could be fixed? I'm willing to
do that if it's seen as a good idea.
