When you run the Komodo it loads all the code intelligence for PHP, Python etc. Very annoying when you want to just work on Ruby. After installation the tutorial instructions tell you to load a certain file. Uhh? Where did it install? It does not know where it installed so you have to manually search to load the tutorial.
There is no way to customize the appearance, no themes. No thanks, I will stick with Textmate for now. Maybe Netbeans might be a good alternative one day.
