[txmt-dev] Re: Question about PlugIns

[bmf]

The ability to independently access and modify each individual 
selection from inside a command or plugin would make TextMate much more 
powerful and life a lot easier for plugin/bundle developers.  Things 
like 'Expand selection to enclosing HTML/XML tags' or 'Wrap selections 
in tag (with multiple selections)' would become simple and quick rather 
than a futile exercise attempting to shoehorn that functionality into 
the current system.

Just my opinion, thanks for a great text editor and a piece of software 
I couldn't live without.  :)  Take care,
Brandon
