Hello folks, we're happy to share with you a new extension we've been working on:
https://github.com/rmotr/jupyterlab-solutions
Back when we were using Jupyter Notebooks, we relied on Exercise (from nb extensions). But then we decided to switch to Jupyter Lab and they were no longer available. So we decided just to take a stab a it and try writing one of our own.
This is just the initial release. We were more concerned about the fact of writing our first extension for Lab, than what it was going to be its final form. We were pleased to find that we could add buttons and several interactions to it; so from now on we'll keep improving it.
If you have questions or ideas, just let us know!
