Drag and drop tabs to workspaces

[Sooperfish]

I would love to be able to simply drag a tab, or a selected group of tabs onto one of the workspace icons and have it be moved there instead of having to open the context menu each time I want to organize my tabs.
I feel this is a much more intuitive way to move tabs and I'd be able to clean up my default workspace in seconds.

I think by default the browser should stay in the messy workspace while cleaning it out, but you could make that behavior toggle-able. Some people might prefer switching to the workspace after moving
(sidenote: is this toggle-able for the default 'Change to workspace' behavior? I like to stay in a workspace when cleaning it out, but it always switches to the workspace I change a tab to)

It would be great if it worked because dragging and dropping is the most intuitive way to move something between spaces, as seen in every operating system.
