Projects should be folders of .lua/resource files, not the .love file.

It's a bit silly to open the .love file as a project. It creates a strange workflow where the love file is extract to a temporary location and using something like "Save All" only saves the version of the files in the temporary location. Instead, a whole folder should be used as a "project" and we should "build" to a .love file. This will more closely resemble the workflow of a C++/C# project in Visual Studio.
