It could be perfect, in my opinion, if it had an option to clean all cookies, except the one in the Whitelist, at browser restart. Update: Thanks! However, consider adding an checkbox option for that, please.
You can. Simply add an expression rule '*' (asterisk without quotes) to the greylist. Entries in whitelist takes precedence. Anything not matching will then fall under the new greylist entry. Feel free to visit our GitHub repo for documentation and FAQs, as well as to request new features or new bugs.
