I would like to see a few changes in account management.
1. The ability to copy an existing account, then edit and save it as a new account. I've seen this requested before but figured I'd include it here as this would be a HUGE improvement over having to create each account from scratch when there are only minor differences between them.
2. Account Limitations moved to the top of the settings window. As it stands, if you make changes to the 10ish fields above the first Limitation setting, then set the limitation, your changes to the first 10 fields revert to default (at least that's what happens to me).
3. A Save and Continue button. Because of #2 (which also applies to selecting the Default Network Device farther down the page as well, I believe), I often change several settings then Submit to save them before continuing. This takes me back to the list, then I have to search for the account again, reopen it for editing, etc. etc.
