would be nicer if you had 2 more options:

1) option to enable/disable "Sort Tabs by Container" within settings with a checkbox or move it somewhere else, where you can't click it by accident. It's more than annoying if around 600 tabs get rearranged when you had them in a specific order …

2) an option to force the current container to inherit and thus override the settings for target tabs during this session only. Use case: online shops have their own container, banks have their own container, thus you can't really pay in an online shop as it switches to bank container and thus loses all important cookies and payment information. Add a tick next to url bar for override during this session and bank and all subsequent redirects would thus get the online shop container but ONLY during this session.
