I use Komodo 3.5.x all the time - pro at work and personal at home. I haven't upgraded because ActiveState want too much money for me to be tempted to upgrade my home version and I don't really want two quite different versions at home and at work. The only "pro" feature I miss at home is revision control system integration btw.

I agree that Komodo is a rather nice IDE. The integration with the Perl debugger is a bit rough (read - crashes fairly often) and there are a few general bugs that are annoying (like debugging context screwing up when a project is moved to a different folder), but otherwise Komodo does a very nice job!

I doubt that 4.x fixes the debugger crashing issues. The context issue I raised as a ticket item and has been fixed (supposedly) for 4.x, but not for any version I have!

In 3.5.x you could (although I've not tried it) add PerlTidy support using commands in the toolbox and the syntax highlighting can be managed under the 'Lang-Specific' tab for 'Fonts and Colors' in the Preferences dialog.
