Building recipes with filters

[Arlen22]

I'm exploring the possibility of using filters in recipes.

A bag is a collection of tiddlers, like a single wiki.

A recipe combines multiple bags into a logical collection of tiddlers.

(Most of you probably recognize what I'm talking about, but that's the generic explanation.)

That way you can have one bag for all your system tiddlers and configuration, and then include them in all your wikis.

More complex arrangements will probably need the ability to use filter expressions to select specific tiddlers from a bag.

Is this a great idea or is it the making of a nightmare?
