Drag and dropping accross lists: add or replace tags depending on state?

[Petri M.]

Hi. I just noticed that if I have a table with rows/columns and if those cells have the <<list-tagged-draggable>> macro in them, then I can drag the items of the list from cell to cell instead of just within a cell. But then I noticed that when I do this I just add a tag to the dragged tiddler corresponding to the tag of the other cell. The old tag is never actually removed.

I fould this thread about this issue and the fix works fine. However, how should I proceed if I'd like to have both functionalities? For instance, depending on a state tiddler or something. I tried to find something like an if else clause but did not really find anything applicable.
