Improving vim mode

[jimzenn]

Including vim mode is really great and I'm surprised that it's so complete. However, there's still some small functions I think can be improved:
in vim mode:

• Can "/" be mapped to command + F, i.e. search, and "n" & "N" also be mapped correspondingly?
• Can there be a simple indicator (a basic one will do, with current mode and instruction inputted)?
• Line number is important in vim when you want to jump from line to line, can there be an option to show line number?

In 3.0.2 (82) (beta that can be found somewhere here in the issues and is scheduled to be released) the following works:

• Can search with / and jump between results with n:
  
• Can run some commands (like replace):
  
• Jump to a specific line number:
  
• You can get line numbers by switching to a code cell and setting the language to text (no highlighting - as in above gif)
• For indication of current mode
  • normal mode: cursor is a red block
  • visual mode: selection appears
  • insert mode: cursor turns into a pipe instead of block

For instruction inputted you can use something like Keycastr (as in above gifs):
