Improve the save system
The save system for your app is terrible. It saves every single edit you make, forever. For example, if I have a document that I change daily, ALL the data that has ever been written on that document will be saved indefinitely, including pictures, whether you can see it or not, in the file. You can see this by looking at the file size, if you use the same document over and over and keep editing it, the file size keeps getting bigger, and bigger, and bigger. Where is this data being kept? Its not viewable. Also change it to a manuel save system with a one click button for saves, including a "save as", because I can't even make one change without ruining the original document instantly.
