I've been using Quicken Classic for PC for (15) years and recently switched to Mac OS, and have found many features are lacking in Mac that exist on PC.
On startup, would like to be able to customize which display is shown (PC allows you to select Home, accounts, budgeting, etc.). I can set that up so Home > Calendar.
PC allows you to edit all calendar displays. I prefer a separate Calendar for each account. Mac will let me setup individual Calendars, but won't let me delete/rename the original "Calendar".
