Cannot search for communities? And some other improvements needed ASAP

Been on digg for a few weeks now but the recent influx of people has shown some significant bugs and quality of life improvements that are required if the intention is to compete with reddit.

1. The sluggish interface - atleast on Android. The app forgets where i was as soon as i switch apps and yes, I have enough RAM.

2. The random log outs.

3. Cannot search for communities and the scolling is weirdly non alphabetical at times. If I try to scroll all the way through, it stops loading after a few 100 I guess?

4. How do I see communities i follow? There is a pin the community option but it also shows in everyone's profile.

5. With the influx, there are many duplicate communities created. Whilst i get may the best community win, it also disengages the users and splits discussion when there are two of the same kind. Some rules regarding communities might be helpful.
