Some very good suggestions, and many I read were things I thought were needed before seeing this thread.

YES, on at least being able to minimize the screen and still sell.
When first starting, and through tier3 the selling process is WAY too long, boring and arduous. I almost trashed the game because of it.

Yes, on stackable seeds! AT least a stack of 5.

other suggestion/wants
the small seed tray from the main does not display the host plants (cross) You have to tab to the seed tray to see it, then back again.
Allow the hosts to be visible from the main seed tray.

2) Display the plant names with the picture of the host plants, on the crosses in the seed trays.
