Even though I managed to install it, I couldn’t figure out how to do anything with it. It doesn’t seem like there’s a keyboard shortcut to run cells. And when I tried to run `import Pkg`, it just gave me an error “Package Pkg not found in current path.” Thus, I wasn’t able to activate any environment and try out anything else, like plotting. On top of that, the program seems to take over the terminal with a light-gray on dark-gray color scheme (as in the original screenshots). Please do not override my terminal colors, which are dark on light for good reasons. I will not use terminals with dark backgrounds as these do not meet my accessibility needs. I would have been interested to find out how well this program handles graphical output, and whether it can handle running inside `tmux` or over an SSH connection (something that in my experience is extremely tricky, and ultimately let me to write a very hacky [MuxDisplay](https://discourse.julialang.org/t/ann-muxdisplay-using-multiplexer-panes-tmux-wezterm-to-show-graphics/132998) for my own display needs). That experience makes me wonder whether a notebook app that is inherently multi-window/multi-tab might not work better if it was sitting _on top_ of a multiplexer instead of a custom TUI framework --- _[View the full topic](https://discourse.julialang.org/t/ann-sessions-jl-a-reactive-julia-notebook-ide/136115)._
