I’ve started trial. Cannot find options to customize indentation for different file types or customize anything per file type.
Also after starting IDE for first time it immediately associated itself with all possible extensions in Finder. Why did it do that without my permission? I’m only testing it, I don’t want it to mess up my existing dev environment. This is very annoying.
For per-language indentation settings check Prefs > Editor > Indentation.
As for file associations, Komodo does not set any associations, this is OSX interpreting your actions and thinking you want to use Komodo for the type of file you opened it with. OSX easily lets you change this back and should fall back on a different editor if and when you choose to remove Komodo.
