Hi @jacquelinett,
Chrome
There are two types of layouts in AQT:
Default Set: The TouchBar layout provided by the app developers
Full Set: These always show for you and replace default sets. They do not hide to allow you to use the app's default set.
Extension Set: These focus on the default set provided by app developers. They provide additional actions but isn't intended to always-show. It's more like a quick actions popup.
In the next update b3.3.0, Chrome will be updated to be a 'full set', meaning a replacement UI. It doesn't close anymore and stays on for you to use.
You can see a preview of it here:
For now though, you can just right-click and select this:
That Bug
This is a known issue that is a bug from BTT. See this thread for details, but TLDR i'm just waiting for the fix to be released.
