Grey out things, fine.
But at least move the cursor to where the filtered item is at, OK?
It still would annoy me. I’m using filters to organise my inventory. I’m using words like ‘dust’ to get mutliple items at once to put them in a chest. They are pretty much never next to each other, so with your solution I’d still have to search for every item separately. There was nothing wrong with the old solution. I don’t know why they decided to reinvent the wheel and create a “new” filter. Everybody knows how a filter should work. 
Honestly it is currently the only bug, which keeps me from playing the game. I don’t mind all the other changes, not even the bugs.
