You are answering my hopes and dreams for a Windows Terminal. The only thing I need after this is split terminals like how iTerm works (so I can have a big one, a small, thing one below it, one on the side, etc). This helps SO MUCH when doing likes like complicated deployments and I need to monitor many systems at once. Is this open source? Is there a way for me to help contribute back? Thanks for the hard work!
