Enventor 0.9.0 landed in Sparky repos now.
Enventor is an EDC editor with some convenient functions. It was started near the begining of June 2013, so expecting it to do everything a mature script editor does is a bit premature.
It is a visual EDC editor with real-time preview of the Edje file.
Does syntax highlighting, highlights relevant parts while editing.
Installation/upgrade from an older version:
sudo apt-get update
sudo apt-get install enventor
