A nightmare the new version

Frozen screen, you can’t scroll fluently, you don’t even have an alphabetic menu/shortcut (so if you hace a file that starts with letrer X you’ll be all night scrolling -if it doesn’t freeze), the search option is teeerrible, it’s all so slow and a freaking mess. I’m moving from this app, can you recommend an app that actual,y works?. The best you can do is downgrading to previous version, and your remaining users will be happy.
