One feature of BBEdit that I've missed since moving to TextMate a  
couple years ago is the ability to open a file Read Only, or even to  
mark an already-open file as Read Only. It's not something I would  
call a key feature that all text editors need to have, but it is a  
great way to protect a file from inadvertent changes (aka protect me  
from myself).

When working on one source file I very often have another file open  
from a completely different project, for reference or for copying  
code from. More than once I've modified the wrong file and  
accidentally saved my changes, then had to use version control to  
revert back. It would be much easier if there was a fast and simple  
way to open the reference file Read Only.

Don't know about the other 2,999 editors that off that feature, tho,  
so I'll let others chime in about that ;)
