feature request: add ability to save tab groups/container sessions

[corey-recai]

add the ability to save tab groups/container sessions, for quick closing and reopening as a way to optimize browser memory usage

the data would be stored in the container management view of the selected container, in perhaps a comma separated, or array-like format [of urls] that can be saved to an indexed db session

you would then be able to close entire tab groups, and reopen them, as well as open individual tabs from each session

this feature would be similar to how firefox tab syncing works
