I've been a big fan of this tool for a while.
I've noticed that development on it has been paused for over a year. This is understandable; there's very little left to be added and functionality wise it's nearly perfect.
However, I'm considering trying to add some new functionality, especially surrounding the interactions between KLE and other keyboard tools websites. Before I began working on it, I was just wondering if anyone else was also working on a similar project.
The current goal is to use the open source of http://kb.sized.io/
to implement git gist usage that can be shared between both sites, and try to get into the source of http://builder.swillkb.com/
for something similar. I'm also looking at taking the mechkeys pcb layout code (https://github.com/mechkeys/mechkeys/blob/master/layout.py
), adding some additional functionality and integrating it with kb.sized.io. Ideally, this ability to use gists for save files and a unified json format for saving layouts will allow for future tools websites to be able to easily start up and integrate with the existing tools.
