the last few days I've been hacking on a equivalent to open_python_file (https://forum.sublimetext.com/t/open-python-files-from-selection-or-current-line/1309/1) for Magento (PHP files). It tries to parse the selections, extract parent class names and tries to find the proper files. Due to Magento having strong filename vs classname conventions this has become easier than I thought .
Grab the code here:

PS The code still needs clean up, but I wanted to get it out early .
