I've been using Quicken Classic for PC for (15) years and have switched to Mac OS. There are many features the Mac version doesn't support that I'd like to see ported over.
I'd like to be able to split transactions by a percentage of the total. E.g. I share an account with my partner and we split expenses on this account 50/50. PC version I can just type in "50%" in the amount and it auto calculates.
