Well giving an option to hide something is never bad. Some people might not like the numbers. I don't really care, but if there would have been an option to turn them off I'd probably tick the checkbox ;)
I find the startup scan to be kind of annoying, can't you make a small index so you don't have to search every time? Cause it seems it's searching every time farr is restarted :)
Why indexing? I find the fact you do not index right now great. It's always up to date. Also, it's super fast so I don't really see a reason to implement an index. If you do so, please keep the option to search real-time :)
