When I minimize the Mobile app, it forgets all data. i.e. if I am looking up a card, then swap to text, then swap back, lost my search history.

Not sure if this is a me problem?
Samsung G S21

also, when selection colors to include or exclude it would be nice to be able to scroll, I can't move the bar so I can barely see White and Colorless.

Adding the gold multi color symbol would be a nice also.

If this is a me issue then I apologize.
