Context : I use Temporary containers. I create a new specific container only to keep a website session open. As it's not often I lose time to first find how to create a new container in order to use the existing contextual menu entry : Always open in this container.
Those 3 operations :
Could be merged into one single clic one single contextual menu entry : Always open this site in a created container
This would create the container with a name took from the domain name of the considered web site (or the page title…) pickup a random color and icon and re-open the site the newly created container, remembering to always re-open this site in this container.
This would help me to avoid the procrastination to keep my sessions (because it's currently too much clicks).
