You're talking about TUIs, which are different from CLIs. As for CLIs, I like ed's UI. It's been shown to be usable for things other than text editors too, like in the web browser edbrowse. As for TUI's, I suppose tinyfugue 5 is alright, but probably not what you're looking for. All it does is separate input and output into two separate panes, and let you switch between instances of these with alt-left and alt-right. Finch's TUI is horrible. It basically tries to look like an entire DE in your terminal. If you don't enable optional mouse support, it's basically a nightmare to use, especially since newly-spawned windows are just spawned in the upper left corner of the screen at their minimum size. Also, OP, what's up with your font? The default font in win10 is different than that.
