The current implementation actually has two ways to operate. Either  
like Dreamweaver or like BBEdit (yes, it's ok to say their name, they  
can take it).

The normal dreamweaver-esque one is repeatable. I don't think the  
other is.
Yes, it does matter which side of the tag your cursor is on. It might  
make sense to make it also work for the opening tag on the current  
line when the cursor is in the leading space of that tag.

TM2 may offer more options as far as activating commands with the mouse.

Also you may want to check out Balance Jr from my subtleGradient  
bundle on GitHub.
That bundle is just a pile of random stuff, so you can just rip the  
specific commands and macros you want out of it and double-click them  
to install in your personal bundle.

Doing a balance command is extremely complex and I'm incredibly  
impressed by Hans-Jörg Bibiko's super-awesome implementation. Although  
I'm certainly not against improvement.
