I wonder if will it be possible to associate user defined clojurescript commands with arbitrary vim keybindings? That would be great! Also, I wonder if there will be support for user defined vim like operators and motions... Or, alternatively, if the plugin architecture will be low level enough to support a vim "emulation" plugin.

Also -- very, very exciting work overall -- visionary even. Kudos!

I wonder how useful these are. It seems like a lot of the functionality of Light Table is accessed through mouse interactions.

With that said, I could still use some emacs bindings :)
