So this is what I see today right clicking a file... I've no idea how long have they been there and I, honestly, don't care. What I care about is that we, as a user, should be able to choose what we want to appears on that list of context menus associated with Dropbox. Because, honestly, 9 items is FAR to much. I can tolerate a few, and I could ignore a few more, but this is far too excessive and has become an annoyance.
If you ABSOLUTELY cannot add a feature to allows user to select what they see, then put all of them in a submenu. That way I can still ignore it to my heart content.
PS: No, I actually do want to use a few of those convenient options (e.g. Copy Dropbox Link), but I really don't care about all these sharing and signature nonsense.
