Focus for YouTube is a Safari extension that allows you to selectively remove parts of YouTube's site to make it have less distractions, hide unwanted information, and have faster browsing speeds.
To include a toolbar icon, I'd need Focus to ask for greater permissions as well as have two panes in the Safari Extension preferences. For that reason, I decided against a toolbar item.
I think it would be quite useful to have a Safari toolbar button for this extension.
Ideal functionality Click: toggle the blocklist on and off. Click-and-hold: display a dropdown menu to quickly customize which items are blocked.
Appearance A focus icon like this one would be quite elegant: https://www.flaticon.com/free-icon/focus_635908
Thanks for the great extension! It helps me avoid being sucked in a black hole of distraction when I watch a video on YouTube.
