Hi Soren,
Nice that you found the plugin.
There is a little bit of a warning! The syntax especially the Glyphs are still in flux. But I can say: "angle" will stay ;)
I didn't introduce the plugin here yet, since it is still somewhat experimental. But today I did discuss with TiddlerTweeter, that it should be more public. ...
There is a "Contents" tab, which you need to read. Starting at Basic. You need to read _all of them and in order_ Otherwise you may get confused.
There are about 80 tiddlers that start with "test-". If you understand how they work, you probably know as much as me about the system ;) They are for debugging atm. But many of them will land in the docs (with much more text :).
Eric's link is OK. .. But please read the docs!
--------------
I'll officially make it "public beta" when I do have some basic videos available, that will explain how it's meant to be used.
have fun!
