JulianEberius/SublimeRope. Very interesting - an integration of Python Rope (a refactoring library for Python code, written in Python) into Sublime Text 2. This will then provide refactorings directly in ST2 - one of the features I have learned to love in PyCharm (especially syntactically correct rename and extract method) and which were previously missing in ST2. I should probably take a look at it, although for projects where I need refactoring, I tend to go straight to PyCharm, simply because many other things come with it (e.g., the integrated debugger). Lately, I tend to switch between editors for simple things and IDEs for large projects, even if you then have to learn different operations - the use cases are just too different to handle with just one tool.
