I've used Textual to build a quick Swedish-English dictionary that runs in terminal but also works using touch, when using the laptop as a tablet and on my Android phone. It was a pretty smooth experience and was very fast to get something working. The TCSS layout system thing is a little strange, but only because I automatically expected it to be CSS and obviously that doesn't really work in the terminal.
