When will workshop mode work?

I'm very interested in seeing Workshop mode work on Forge. I have a couple friends who design cards using Magic Set Editor 2, yet playing with their cards as designed is not entirely available to them. I've made ways of short-cutting the process of importing cards from MSE into Cockatrice, but it's cumbersome.
Being able to change cards scripts, import new cards, and learn from how other cards are scripted would make for a fun hobby.
The issue I'm having (running 1.5.25) is that when I go to Workshop's tab, and select a card, nothing appears in the script box. It's been like this for quite some time, and feels like wasted space, honestly. It'd be great to have a working script editor.
