The UIs are text only, so they are textual. Modern TUIs may support mouse events. That this tool can export to several TUI frameworks is evidence that these UIs are indeed TUIs, even if not the most traditional.
It clearly cannot. Have you even tested it?
I guess the headline and website was enough to get all these upvotes. Quite disappointing as someone in the early stages of making a TUI tutorial myself.
100 percent agree. I personally love what the openTUI folks have been up to. As weird as this might be to say, we're still in the early, early stage of TUI adoption.
