Not to be dismissive, but I have no idea why I should want to install this. I actually just spent a few hours setting up a tmux configuration
yesterday, so I feel like I'm in the target audience for this, but...
I can configure panels with YAML, it looks like. Why would I want to change my resizable panes for a set of static ones? It supports arbitrary plugins, is says. But can't I just run any program in tux, so what is the point? The screenshots seem to mostly show how loud and colorful the chrome is, which seems distracting. And then the roadmap seems to be the only feature list, does that mean the software is actually "batteries-will-eventually-be-included"?
