But, I'm stucked at version 5.7.5

Yes, you get shocked because the current version is 10.0!
I tried some new version but still have the same problem. Well it's not a problem but is related with the difficulty for filter.
I work with lots of databases (632 right now) and i need to filter quickly. In the version 5.7 and previous ones, after you click on a bookmark, you go to schema editor tab, then you can press keys and automatically the list of databases gets filtered, and then you click one database and you start filtering tables with the keyboard without doing nothing, and same happens with fields.
This is very important to me because im moving from databases and tables all time.
My surprise was when in new versions you need to click on the filter box to start filtering, this started to dificult my job, but I thought "maybe i could try to get used", and then the worst change was when i saw that i can't filter databases (there is no box!).
I'm not sure why these changes, the ease of working the old way is much better than the need to go typing in a box, and i didn't had any problem with it in years.
Maybe more people had the same problem, maybe engineers decide to recover this awesome feature... ;D
Thank you.
