I have Ubuntu Mate installed on my Pi and I'm pretty happy with it, no problems. However, the built-in terminal application is definitely not designed for touch screens, nor the file browser or any other built-in app. What I mean is, for example, I can't swipe. I have to use the scroll bar. This is not the case for Chromium, which isn't built in.
Are there any terminals out there that can be used with a touch screen? Also, I would be really happy if you provide replacements for other built-in apps.
By the way, my touch screen is WaveShare 7-inch 800x480 Touchscreen.
