How to Change Quickly's Editor?

quickly should support the EDITOR environmental variable.

$ quickly help ubuntu-application edit
Usage: quickly edit

A convenience command to open all of your python files in your project 
directory in your default editor, ready for editing.

If you put yourself EDITOR or SELECTED_EDITOR environment variable, this latter
will be used. Also, if you configured sensible-editor, this one will be
choosed. 

I don't have any other GUI IDEs installed, but I tested it with $ export EDITOR=nano && quickly edit and all files were opened in nano instead of gedit. Adding export EDITOR=nano to your ~/.bashrc should make this change persistent.

If you don't want to change the default editor for your system you could just use

export QUICKLY_EDITOR="yourpreferrededitorhere"

I found this somewhere on the net, so credits go to the guy who discovered this solution.

Cheers
