more_minimalist_gmail.css is a userstyle that hides most of Google Gmail’s UI, leaving simplified view of your email, labels, and search box. It’s intended for people who primarily use Gmail via the keyboard.
It was inspired by Matt Constantine‘s Minimalist Gmail browser extension, which I used for a while and liked. It’s out of date, though, and the userstyle goes further, hides more, and since it’s a userstyle, is much simpler.
- Use keyboard shortcuts! This userstyle expects that you do; it’s pretty much unusable otherwise. Details here. (There are a few undocumented ones too, including – in the new UI – Ctrl-Shift-T/C/B to jump to the To, CC, ex BCC boxes.)
- If you’re using Stylish, you can temporarily show the hidden features by turning off Stylish. Click the Stylish icon and select Turn all styles off. When you’re done, select Turn all styles on. Bonus tip: if you do this often, add a keyboard shortcut with keyconfig.
- You can hide individual labels in the GMail settings Labels tab. This includes built in labels like Starred, Important, Chats, Circles, etc.
