BTTV ported to Microsoft EDGE

Unfortunately we are not able to upload to the store until Microsoft makes it possible. Right now they are only allowing whitelisted applications to upload extensions to the store. We’ve tried and gotten this error: Package acceptance validation error: com.microsoft.edge.extension is a reserved extension type. Your app does not have permission to use this extension type.

Alternatively you can actually install tampermonkey for edge and then use the userscript version of betterttv found on the website:

This is just a temporary solution until microsoft allows BetterTTV to upload directly to the store.
