First of all, great to see AdBlock in Edge!
Unfortunately its still a pretty basic version and lacks many features.
This feature I'm missing the most is an easy way(1-2 clicks) to whitelist a website.
The Idea (its already present in other browsers) is to have the option in the context menu. This could be either the right click context menu on the website itself or on the adblock icon next to the address bar.
Many thanks :)
