Nice Addon ! :-)

Would also be great to extend this Addon to "PASTE FILE FROM clipboard AS ATTACHMENT".

Because currently there's no way to paste a file from the clipboard as ATTACHMENT into a compose window by using the Ctrl+V keys (as in MS Outlook) or by using a mouse-right-cklick (context menue grayed-out).
Using Ctrl+V only results in inserting a text like "file:///C:/Test.xls" instead of the file itself.

Okay, it's possible to attach a file by dragging/dropping or clicking through the menu/searching for the file... but it's unconvenient and time-consuming.

Hope, you can help (= enabling Ctrl+V and right-click-contrext-menu).
Thanks ;-)
