Granting users the option to donate 500 or 5000 lemon coins in one go instead of 5 diamonds or etc. could be a way to minimize spam of alerts and also give people more options to donate between larger amounts (100 vs 1K and 1K vs 10K).As far as naming them goes, I'm sure the team could come up with something creative, but I'll offer perhaps "gold bar" for 500 and maybe "ninjayacht" (or the punny variation "ninjyacht") although I'm sure you could think of something more clever. :)
