Just tried it out! Pretty great. Reminds me a conkeror a lot.
One nitpick though: I feel like you should be able to open a new buffer with C-x C-f, and maybe open in the same buffer with C-x f? C-l in emacs centers the text on where your cursor is, so using that and M-l to open links/buffers feels a little odd.
Edit: Also, I don't know if you maintain the AUR package. But I had to install libfixposix manually as it wasn't listed in the dependencies and had to restart the compilation from the sbcl debugger.
