Snaked

Very light and minimalist editor inspired by Scribes. Snaked intended mostly for python developers but other Scribes users may find it useful too.

Shortly, Snaked is Scribes with blackjack and bitches.

Goals

As little code base as possible. GtkSourceView gives enough features. Editor core should only implement project, shortcut, plugin, editor title and editor problems abstractions. 1000 - 3000 cloc's of python code estimated.
Clean and maintainable code design. Say no for Scribes signal passing hell.
Tabs! I'm using awesome tiling wm, so Scribes lacking of tabs is not a problem for me. But many users complain about it.
Speed. All development will be maid on Atom Netbook. Scribes is too slow on this hardware.
Memory footprint. Scribes internals is too complicated to trace all object references and editor leaks like bloody shit. Weakrefs will save the world.
Flexible plugin system based on standard python packaging practices.

I use Snaked for all my python development tasks. Following features are implemented:

Quick open on <ctrl><alt>r.
Goto python definition on F3.
Complete words on <alt>slash.
Pretty title for python modules.
Python code completion on <ctrl>space.
Smart block selection on <alt>w.
Storing last edit position for every file.
Python smart indent.
Saving quick open project history and switch between them on <alt>Up/<alt>Down.
Tabs. Switching on <alt>Left/<alt>Right
Python outline navigator on <ctrl>o

Current progress may be seen in @a_bobrov.

Features to implement in nearest time (day or two):
