They way I work with spreadsheets is to keep a task per row and then I add a few status columns to help create various views.
I can do this in TiddlyWiki by opening each Tiddler and tagging it, using tags as the status column.
This works, but it gets cumbersome after about five or so tiddlers.
What I'd like to do is use a filter to add or remove tags to a set of filtered tiddlers.
Ideally, I'd like to see this function as one of the buttons on the "Advanced Search" / Filter page. Alongside of the filtered export and filtered delete functions.
I've been looking for a few days, assuming this is a common thing to do, but so far, I've had no luck.
Is there a way to do this?
