[Catalyst] What text editor to use?

[John M. Dlugosz]

  What's a good text editor to use for Catalyst/TT development?

The editor I really like for C++ doesn't handle XML well.  I've been using "Notepad++" for 
windows, but the syntax highlighting doesn't understand mixing TT inside the base 
language, and it has tabs only instead of multiple visible windows.

I would entertain both Windows and Linux solutions.

TIA,
