IMO Chrysalis 0.4 removes the Ergodox advantage of the online configurator. It’s now better than the EZ version (the bottom pane is much more usable than the dropdowns you get with the EZ tool), and it will obviously keep getting better still. The next ask on my list would be to merge the colour editing with the layout editing (one main screen, two tabs below, one for colours, one for key mapping). It would be nice to be able to set a default colour for the entire layer (as you can with ErgoDox) and then be able to override that default key by key.
Macro building might be nice further down the line.
One question - if I were to modify the “num” key function in the first layer, would I lose the default colour behaviour (i.e. the “num” key goes blue and the active keys in layer one go red)?
