Using tags to add existing notes to the kanboard

I'm aware that Tag filter is already present, and it is great.

But i have an additional suggestion

Use 1 tag for the kanboard (as currently impemented) and add 1 additional tag per column.
This way, setting the tags will let the plugin in which stack it should be displayed.

One example use case where it should be useful for instance :
I want to add an existing issue to the kanboard.
I have to search it by name using the search box
once found, the focus to the kanboad is lost, the found note is displayed, hard to drag and drop it ....

Start by tracing the existing Tag filter, kanboard column handling, and the search box behavior. Determine how tags currently select notes and how columns render them, then verify that an existing note with a kanboard tag and a column tag appears in the intended column without requiring drag-and-drop.
