Personally, as nice as it would be, I think another column on the register would be starting to get too much (perhaps, as I'm fairly neutral on this at the moment

). The cheque/check number could be put into the comments just as easily enough.
The reason I am using YNAB is because it 'makes budgeting twice as effective in half the time', is simple to use, and does what it is supposed to do very well. Most recent additions are most welcome, and I feel they fall in line with the aim of YNAB, but I feel eventually we are going to get to the point where we are going to try and add too much. YNAB was never designed to replace programs like quicken etc...We could add features here, there, and everywhere, and perhaps eventually lose sight of what YNAB was really trying to do eventually..
Actually, I'm not fussed either way, I never use cheques, and I am a gadget man that has a gadget/spreadsheet/program for EVERYTHING, so it could never be too complicated for me...perhaps I have just put this argument forward to play devils advocate a little
