Interesting idea and project. The browser's UI is very different... and lacks some (most) customization options... I spent a long time looking for a way to increase the font-size, for example. (Not all of us are accustomed to squinting at phones.) Preferences to set: I thought that was hiding, but it seems to be missing. Say what?
After an hour toying with the interface: technically it looks to have a lot of possibilities. I have serious concerns about the lack of transparency ... unlike most browsers today ... what's going on in security, ad-blocking, tracking? I found no way to tell.
In sum, cool project. The potential is clear. I can't imagine anyone non-technical not running away on first sight. It's more opaque than Ello, even. More like an oscilloscope than a mobile!
