Something I noticed after @PMario solved my popup-issue
https://groups.google.com/forum/#!topic/tiddlywiki/C9IujCV8S0gEach time I open one of the popups, my TW comes into a "has to be saved" state.
Understandable as it will alway create a new tiddler to store the popup's current state. Is there any way to render these tiddlers as not-to-be-considered-for-saving?
It's a bit annoying as you cannot be too sure about whether or not you actually need saving or not.
Or is it just me who doesn't like this?
