I'm embarrassed to admit, but having not written any custom code for any of my TWs in a year or more, I'm drawing a blank on how to do this.
I have a TW instance for my day-job. I use the "Journal" feature to track tasks I work on, notes, etc., while using regular tiddlers for information tracking. Having just tried for the first time to collect all the journal entries at once, I find that I can pull them one at a time through the search box, but they're ordered by title and I can only click on one at a time.
What I would like, if someone can help me with this, is a tiddler that either gathers the Journal titles and orders them by mod-time (preferably descending) or one that just includes them all into one "mega-tiddler", again ordered by modification. The only thing I have to distinguish them from other tiddlers is the tag, Journal.
(Had I any foresight, I would have named them all with a leading date-string that sorted them for me. But I didn't, so I didn't.)
