OmniOutliner 4 for Mac saves files as packages, which is really folders with files in them, that the Finder displays as single files. Inside the package is a contents.xml file - which is in reality a zip compressed xml file.
Is there a way to save .oo3 files without the compression so it works properly with version control systems?
I know I can save in other formats, but they don’t retain all the information about styles, formatting etc.
If you’re using git you probably want to use a “textconv” option to unpack the file in your .gitattributes. Kind of like people use strings to diff MS Word files.
