If you like me, and you don't like the Curse Twitch client, I have made an replacement for it. You can get it from : https://github.com/polenplein/WoW-AddonInstaller It's totaly free and published under the GNU-GPL3 license. Source code also there if you want to compile yourself. To compile the source code you need QT >= 5.9 and QtCreator installed. (it's also complete free to download if you choose the community release.)
