How would this work? are there system tiddlers that govern virtual tiddler layouts? Is it more css magic+ some java? I am saving some small image galleries, and I want to tag all pics in one gallery/slideshow in one import.
I also suffer similar tagging problems in advanced search, as sometimes I wanna export tiddlers with a certain tag, but only *certain* tiddlers, say, 4 out of a dozen, not all of them. I love the 'search and replace tags' plugin, it seems that tags and checkboxes go very well wherever they meet (though, perversely, that plugin needs a 'select all' check box. At least it gives me confidence in the potential) .
As for the drag n drop, in case you are interested, I got the idea from the current version of PotPlayer, which has two 'drop' zones-an 'add to playlist' strip and a 'play now' box. It's decadent; I don't know how I lived without it before.
