Are you hardcore?
Then Ultimate Tag Warrior 2.0 alpha might be for you!
This is still somewhat non-shiny; but it appears to be backwards compatible with 1.1.2.
The bundled zip file contains enough information to get you into trouble; but probably not quite enough for you to get it working if you aren’t familiar with existing Ultimate Tag Warrior installs. (In fact, if you’ve never installed Ultimate Tag Warrior before, there’s a pretty good chance that it’s going to steal your lunchmoney.)
Long story short: shiny new code, lives in wp-content/plugins/UltimateTagWarrior (since there are now.. five.. files to it, I think). So once you’ve copied the plugin there, you’ll need to disable UTW1ish, and enable this version. The rest of your install should “all just work the same as it always did”.
If you’re feeling brave, by all means; start using the functions in the core class, and playing with the formatting bits (There are formatting bits! They allow a big bucket of control over the way lists of tags get displayed. All of the lists (I think..) in UTW1ish have been recreated using formatting strings. There’s more about that guff in the help file.)
Oh yuh! Just for Dan, there’s now a lazy-tagging thing that will display a list of all of your tags on the edit screen, and allow you to click on ’em to add them to the list of tags for the post.
And for….Cliff (I think?), tags can have spaces, sortof – if you enter tags with _’s, then most of the time* the formatting stuff will automagically display the tags with spaces (but link to the _’ed name)
* except in strings where you ask it to do something else – the standard %link% things will do the space thing.
