This is a simple idea that could improve usability of filters a lot.

Currently, when one drags a message from the one folder to another, a menu pops up asking which action should be taken, "Copy", "Move" or "Cancel".

I suggest an additional action: "Create Filter".

Selecting this option would create a filter based on sender (or on mailing list, if List-Id is available), with the action set to move to the folder the message was dropped to.

Things to consider:

* whether this applies only to messages dragged from the inbox or from any folder;

* whether this Create Filter option opens the filter configuration dialog (with action already set to move to the folder, of course) or not;

* whether the filters get applied to the inbox automatically after the filter is created.

(The last two could probably be configurable options.)
