Works for the NOTES.
Is grayed out for the recycle-bin, and folders.
However, I have a "read_only" set on the recycle-bin, and the option is stilled grayed out. Does not appear to cause a problem - is it?
I had a folder show up with "read_only" set. Again it did not seem to cause a problem, but the setting could not be changed. I created another folder and moved the contents to the new one and deleted the old one.
I think a "read_only" flag on folders would be a great addition.
