I LOOOVE this app!
Just one thing we really need, aside from the landscape screen option already noted:
Ability to Progress Bill so that when we do a 2nd billing, it will only show what hasn't been billed for. Currently, we edit the first invoice and do a percentage of qty (ie: usually we have a lump sum billing, so qty is always 1, we edit to .50), send out bill. When we go in to do second billing, it shows original estimate amts. It would be awesome if it showed only remaining qty's to bill.
Thank you for this awesome app! It has saved us a lot of money!
