I would like to see ZIP-Files be handled like folders today, creating an archive format.
One could open a zip file exactly like a folder. Editing files would update the ZIP.
Also, if a sublime-project file would be found in root of the ZIP, that file would be made the active project.
Single File projects that could be easily shared and filed. Mostly of interest for MarkDown documentations and similar projects.
There is a ZIP plugin that already gives access to ZIP files, but I envision a bit more.
Maybe this can be done with a plugin?
