What Are Some Cool Extensions You Use?

[Juan el Demgrafo]

I recently installed a dark-mode extension to my Chrome and it made me think: what other cool things are there that I and other people mightn't know about?

My Favorites That I Already Use:
Universal Dark Mode for Chrome

Save files to Google Drive (requires a bit of configuration in the options)

Lets YouTube will play at 60fps on Chrome
(A nice test for this)

Software keyboard for typing without tapping

Software keyboard for writing with a stylus

You can customize your default fonts on Chrome in it's settings

You can add text replacements to you phone and computer so you can easily use your Japanese emoticons. ﾟ･✿ヾ╲(｡◕‿◕｡)╱✿･ﾟ (There's likely a keyboard for this, but I prefer to be able to just type something instead of searching through an endless list of these)
