I'm working on 2 things right now (on side). Both commercial (sorry!).

First one is RACE terminal [0]. It's a put-terminals on infinite canvas terminal multiplexer. Right now on macOS, but soon I expect to have Linux version fully released.

Second is Inboxctl [1], it's a keyboard-driven mail client for power users.

The cool thing about both of them is that RACE is my terminal multiplexer and Inboxctl is my e-mail client and they work great. I'm really proud that I can fully interact with terminals/e-mail using my own creations. Both are based on the GUI-framework I accidentally made for ascdraw [2] and kakvide [3].
