I really really like the instant filtering box in dolphin (besides the lack of wildcard recognition) but often I end up filtering for something and then wanting to remove that filter and I click the “up” button which results in going up one level. But in my eyes the filtered view is a “depper level“ of view which should be first cleared when pressing up and then when there is no filter applyed then it should go one level up.
And those who don‘t like that could either disable that feature or double click on Up (clear filter, go up)

Reproducible: Didn't try
