Recently gave this language a spin with raylib and libtmx for loading tiled maps. Out of C3, Zig, and Odin, I've had the least trouble integrating C libraries with C3 (rolled my own bindings for libtmx). Overall a big fan of the language and am hoping it gets recognition on the level of the other languages mentioned here.
This looks pretty nice! I like the ability to add multiple file panels versus tabs that are common with nnn and ranger. Going to give this a spin today.
mike_h has some good advice, deconstructing other people's songs is a great way to learn Renoise. The forum was pretty friendly when I was active, and people post examples frequently, so that's a great resource.
I also recommend learning the keyboard shortcuts like the back of your hand. It really helps with keeping in flow and is one of the biggest advantages of the tracker interface.
