LXTerminal.
I don’t know if increasing the font size counts as customization. I’ve got old, tired eyes.
Transparency is also turned on, which I think I did with compton. It was a long time ago and seems to persist through Debian’s dist upgrades.
It’s worth adding that the entire LXDE suite is great software. It just works. I hope I don’t have to give it up any time soon.
Ottawa breathes a sigh of relief.
