Well the Curseforge Overwolf app open alpha has started
It’s not too bad.
You can turn off it starting at boot time and it actually respects that setting (nothing in the startup list or in the registery). You can also get it to quit when you quit it and it doesn’t appear to leave any overwolf processes running. Overlays are turned off by default.
I made a thread in the UI & Macros forums on it -

PS Yeah I tried it in both a sandbox and on my main install. Looks fine to me. your mileage may vary.
