Feature Request: Tag quick access pane

[Mistmage]

I really like the ability to drag and drop full and ready tags.
The problem is that i have way too much tags and i can't organise them, and honestly it is a bit laggy.
I would loved an ability to create separate page with selected tags, just for drag and drop.

I found that i can create similar effect just by selecting and dragging any text (including a tag) from prepared note, but selecting really not the best experience.
