used to use tabsoutliner for the longest time, which kept me on chrome, but missed the option to export trees separately. Finally took the plunge and this fits the job. At first a bit confused about tabs just being hidden, which caused trouble with twitch tabs auto-redirecting by the hosting/raid feature, but I have since found out that you can turn this off.
Glad to hear it's working well for you, and thanks for letting me know about the Twitch issue! I'll look into whether something can be done to address this.
