Its based on webkit, IIRC

Thank you! It's a Qt, chromium-based browser with keyboard-centric navigation. It's modal, like Vim, and with Vim-like key bindings, so you can keep your fingers on the keyboard and not have to switch to the mouse and back.

here's an explanation from Bread on Penguins

I believe it's a cef (chromium) based Qt browser

Thanks. It took me a while, but the status bar icons and text are also conditional (using bash scripts with if/then statements and case statements). I also created separate picom animations for notifications and windows.

Thanks! That's the tab bar. The icons are minimized because of the window's size, but you can see the icons when the window is maximized. It also allows mouse scrolling.
