Judging from my five minute test drive, you could probably increase adoption if you made it 'discoverable'. It's hard to determine what to do once it's installed. Turns out, you have to click the browser action to start listening for user input. After that, you have to refer to the website to find out what commands are available. It would be great if there were on-screen suggestions of commands to voice. Using it was really frustrating and unreliable until I read the instructions on the web store page to disable 'ambient noise reduction' on macs. Showing an 'instructions' page on installation would help a lot. An instructional video would be great too.
Other nitpicks: * I couldn't get dictation to work. * More tab manipulation commands would be nice * I'm not a huge fan of the link hints placement and styling
I'm actually developing my own keybinding extension like Vimium/cVim/VimFx/Surfing Keys
https://github.com/lusakasa/saka-key
with the intent to use the codebase to later create a voice commands extension like yours.
After all the work I've put into my extension, I can see why only $10 in donations for your efforts is disheartening. Good luck!
