I have a laptop that I like to watch youtube on while doing other things on my large monitor, but I noticed that when using the theater mode, a significant area of the video is covered by the search bar. On the big monitor it works fine, but I want to use the small one so that I have the big screen free. Is there any way to fix this? Ideally I'd prefer not to use fullscreen because I personally despise it.
I recommend this Chrome extension called Improve YouTube! (https://chrome.google.com/webstore/detail/improve-youtube-open-sour/bnomihfieiccainjcjblhegjgglakjdd).
This extension allows you to change a lot of things, including appearance options.
Step 1 Select the appearance option from the extension menu.
header from the appearance menu.
hover in the popup dialog.
For changes to take effect you might need to refresh the page the first time. If the extension icon is grey the extension settings are not active.
