I think there should be a better way to do these things.
For example screenshots (great that now we can rename the files). How could I share, send or save a/many screenshots in dropbox/onedrive/drive… or send by email. Now it’s a bit tough or difficult, you must open a different app and search and load the file/s.
I’m not very sure if there are folder of these apps (dropbox etc.) in the folder tree of the device to copy/cut and paste. I can’t find them.
I think that when you long press in a file or folder there should be an option in the menu not only to rename/erase/copy/cut/open with etc.) but also to share/send to/by another apps.
