I would really appreciate it if Trello would implement a way for a user to customize their keybindings for all of the navigation shortcuts. I use Vim when programming, so I really appreciate that I can go up and down the cards with j & k, but then I can only use the arrows to move horizontally. I don't think this would be a hard feature to implement, and I have a feeling that it would allow some users to massively increase (if not, at least feel as though they are and be more comfortable doing it) their productivity and ease of using the app.
Has anyone found a way to do this? Or is it just not a feature?
