[MonoDevelop] Contributing to Monodevelop: ViMode

[Ryan]

Hi all,
I'm interested in trying to contribute to the Monodevelop project, 
specifically the embedded vi editor mode.
I've found this list of TODO items:
http://monodevelop.com/Developers/Tasks/Source_Editing/Vi_Mode
but I'm not sure if its up to date. The current master branch of 
monodevelop doesn't seem to have any of these features but I don't know 
if somebody else is implementing them yet.
Does anyone know the current status of ViMode in Monodevelop?

Here are some of the features I'd like to implement:
1. Multipliers (e.g. 5dd, 4>>, 3cw, 7@@)
2. Goto line (44gg)
3. Word end movement (e, E)
4. Inner/Outer motions (ci{, da])
5. Find motion (f)

I already have tentative solutions for 1-3, but they aren't very 
thoroughly tested, as only I've been using them.
Let me know if these are already in the works / implemented somewhere else.

Also, if anyone has any general advice with regards to contributing to 
monodevelop, I would appreciate it. I'm somewhat familiar with Git but 
have never contributed to a large open-source project before.

Thanks,

Ryan
