Yes, I've got one (a slightly earlier release) which I've been using as a logic analyzer. I have some other ideas for it, but to customise the firmware I'll have to learn nmigen which presents a barrier to the non-python-literate. With nmigen, instead of just writing some verilog to describe a design, you have to figure out how to craft a python program which will generate the verilog you wanted to write in the first place.
