[suggestion] Option to delay deleting limited lifetime containers #190
Description
One useful feature of the Temporary Containers extension is that rather than deleting a container the moment the final tab is closed, it waits for five minutes so that you can undo closing the tab during that time. It'd be convenient to have that here, since while Containerise's ability to automatically add rules to temporary containers is super handy for keeping each session intact, the way instantly deleting a container interferes with restoring tabs is unfortunate.
