Macros support for keyboard shortcuts
I love Vivaldi because it's the emacs of the browsers — I love power tools with focus on keyboard shortcuts.
In that respect I'd like to see support for macro where I can bind several steps to one shortcut. Example is "focus mode" where I'd like to hide everything (all the chrome) but the page content itself.
P.S. I'm aware of 'Toggle UI', but I might want to customize it by having the panel bar open.
