Mint.com is tearing it up these days, and almost blew Wesabe completely out of the water if it hadn't been for wesabe's recent new features. After a few minutes of using the UI I realized a core feature had changed for the worst, assigning categories to transactions.
Its used to have a popup that contained all the transactions, and you could quickly find the one that you wanted. Categorizing a long list of transactions was relatively simple and fast. Here's that list:
The new version of this is a drop-down that you have to mouse-over to find the subcategories. Its a real pain, and put a serious dent in me keeping up with my tagging/categorizing. They do have an auto-complete, but its a hassle to tab over to that field, and you can't just hit the "enter" button to save the tag and go back to your transaction list. Here's what it looks like now:
The other issue with this is, that you can't bulk edit the merchant and the category independantly. If you select 20 transactions, and want to make them all a certain category, it changes the Merchant name for all of these transactions to "Multiple Merchants". I lost some data this way!
Oops, in the making of that screenshot I accidently clicked Save and lost two more Merchant names!
Anyway, Mint.com is still my favorite personal finance application, and I havn't been searching for a replacement. These small quirks are a big enough pain to think about wesabe or buxfer again.
