Give the ability to hide the total amount a client has paid on Customer Detail - It's Tacky
I love seeing how much a particular customer has paid (Total Invoiced). What's really tacky is not being able to hide that when you are pulling up the screen and the customer is present and can see the screen.
There should be a way to toggle that on or off.
While I agree the customer could run their own reports of how much they have paid if they use Quickbooks, having it always on is, as I said... Tacky.
