I think before you can answer that question you have to figure out if there are enough geeks like you who think this is a useful enough tool to run / use regularly. They'll likely pay you $. Alternately, find use case where even just a few users / companies would pay $$$ each for some thing that it does that you can't easily get anywhere else and helps get work done.
For me it looks cool, and i'll give it a try, but i'm more likely to stay with my normal browser because with plugins like vimium i don't have to reach for my mouse very much. That's actually one of the reasons i use the command line so much. Make it work without constantly using my mouse and I'd be far more likely to use it. Once i'm using it regularly, then I'd be starting to think "I wish it would..." and then making those wishes come into practice is something i'd support. This is kind of a weird / esoteric thing that would just gradually improve so... maybe Patreon is a better route for getting support than normal software / feature / plugin sales.
personally, IF I find myself using it regularly, i think i'd be more likely to support you via a Patreon type regular donation.
