I was just wondering if Komodo Edit lends support for writing Java files or not?? I know I can do Javascript in Komodo but how about Java?
The Java language is not supported by Komodo, or rather, Komodo will only provide code coloring for Java.
Whatever - you can add Java support by creating a new Komodo Language from Projects (Project - New From Template - Create Komodo Language 
)
If you want more Java features(maven compilation, etc…) You can always write a plugin to do it. In fact, in a few months I will be creating a plugin aimed at either Play or Spring development.
Note we’re working towards setting up a reward system for people that make big contributions such as the one you described, more details to come 
The stickers? 
At the very least.
“Happy” won’t come close to describing the wave of emotion when I finally get Komodo stickers.
