Hi!,
So i've been using luci-app-nextdns for a while and it works very nice also on a bit more advanced setups, but I also looked into controld but then I could not find a package for it for luci.
though controld themselves do have options to download the CLI from their site not in a opkg format afaik.
but I wonder if someone might be interested in creating a opkg like this? 
why a package?
well some of these dns providers do have options to have different profiles, or even client scope like nextdns does, controld for example also has a interesting proxy feature, and I also readed that controld has support to also combine support to nextdns aswell...
on the other hand I can understand also if developers say to not add it since nextdns and controld do have also alot of commonalities.
is it a good idea ?
many thanks
