<<tiddler [[Dwarven Religion/summary]]>>
...and then I can see the summary text on the overview page.
The other useful plugin, here, is [[TiddlerWithParamsPlugin]]. It implements what those MediaWiki types call "transclusion." It's "inclusion with translation." You can include a tiddler's text, but replace variables like
$1 with arguments passed in. I am very excited to share this possibly banal hack: I made a tiddler called Summarize. It looks like this:
//see main article [[$1]]//
Then, in my "Dwarf" article, I can actually write:
<<tiddler Summarize with: [[Dwarven Religion]]>>
...and I get a section that looks like this:
//see main article [[Dwarven Religion]]//
Dwarves worship Tossy the Far-flung. Blah blah blah...
Holy cow! Along with the DisableWikiLinksPlugin, these make me feel like I'm running a fast, prereq-free MediaWiki install.
The final plugin that I'm using, now, is BreadcrumbsPlugin. It adds breadcrumbs to the top of the page as I navigate around, which help me remember what I was working on before I digressed five levels down. Unfortunately, it doesn't interoperate with my gotobox, but that's my problem. I'll fix it sometime soon.
The main thing that continues to bug me is the lack of a good catalog of plugins. Some are listed at TiddlyWiki.com. Others are tagged as TiddlyWikiPlugin on del.icio.us, but that's nigh-impossible to use as a useful reference. There's TiddlyTools.com, but it's slow and hard to use. At least one of its pages basically crashes Firefox, possibly by playing a lot of MIDI music at once. Why does this matter? Well, the default TW search behavior is to open all matching tiddlers. I probably would've found the PartTiddlerPlugin a lot faster if I'd been able to search for "include" without crashing.
Still, I remain a fan. I'm hoping I've finished the "make it work the way I want" yak, so I can start to get some "serious work" done.
