Quote, Invoice, PO Templates

Hoping that we can have a tab that gives us access to either create or edit our existing PO, Quote and Invoice Templates vs having to access them through the actual PO, Quote or Invoice. It's very hard to read and format the entire text bc the box is so small. It would be great to be able to see it in a full screen window. In addition to it would be great to be able to edit the templates without having to save new ones. It gets very confusing.
