How to hide pencil icon

[AKikhaev]

It's useless for me. I want to remove it forever

Currently there is no native option to hide it.

One solution to hide it is with the uBlock Origin extension and with the following rule in "My filters": youtube.com##.cbSubmitButton.
If you are on Google Chrome, uBlock Origin is not available; use uBlock Origin Lite instead. "My filters" is named "Custom filters" in the latter.
