Feature request - allow whitelist domains to be retained when extension is reset

[wellloaded]

This is the most annoying part in using the extension (on Firefox at least).
Occasionally it gets stuck, and I'm asked to reset the extension.
No problem but all the settings are gone when doing so.
So I'd advise to find a way to retain:

• whitelisted domain (split tunnel)
• favourite endpoints
• other settings...

So assuming it might be "a" setting that crashes the extension you could provide a way to import/export to conf file, which can be manually edited if ever needed, I suppose. To be fair re-adding the domains manually every time, is not viable.
