Since the latest update scrolling through your active and available mushrooms can be a bother because of the number of mushrooms so how about an option to tap a mushroom and pin it to the beginning of the list?
Also, I’m always zooming the map out as far it is goes so I wouldn’t mind a setting to set default map zoom! (Something like 0%, 25%, 50% you get the idea..)
There’s also something else I was thinking of but I can’t remember right now 
Scrolling hasn’t improved for me either. I don’t want to see the mushrooms that have already been filled up first (5+players), I want to see mushrooms with vacancies first, preferably giant event, giant elemental, event, elemental, regular, and small.
In fact, I want the option to toggle visibility of filled mushrooms because I don’t want them clogging up the list for hours. I still want ability to untoggle because sometimes I like to join a 5+ participant battle if it gets filled near capacity or really high score .
