Okay
Sorry for the commit spam - i can redo a fresh new PR with commit history

failing miserably at the drop thing when the same code works for eOS

so, for the "just click on the title name and type to rename it" feature - sandboxing prevents the app from doing so. It sends the file to oblivion
So either i drop this feature idea,, or user wide access gets added to manifest.

Which would you prefer ?

I prefer tabling the feature for now, until we can think of another way or another feature also requires opening up the sandbox to that degree

Yeah. Id have gone for the same route.
It's just not important enough for this much
