I doubt that this is a new idea. It is frustrating though. I've been using Quicken for about a week now. I used Quicken for the Mac early on until they stopped making it for the Mac. I then switched to Banktivity from 2003 until now. I decided to switch back to Quicken because Banktivity has some frustrating things that they have never addressed in 20 years.
So now back to Quicken… I love everything so far except 1) the Split Register (which I use for credit card transactions). You cannot remove columns you don't need (like transfer). Also you cannot adjust the width of the columns. I need more room for the Memo/Notes column. 2) I find it annoying that I cannot have two registers open simultaneously. I was able to do that in Banktivity. I take care of my husband's checkbook on a separate file and I need to be able to transfer transactions from his Split Register to mine and vice versa, as I have a small business and I need to make journal entries. Maybe instead of two registers open at the same time, take that "transfer" column and give it more valuable functionality. Let that column allow transfers to/from another Quicken file! 3) "Drag and Drop" transactions inside the Split Register would be nice.
