Twitch Features:
Switched Global Emotes to new API
Some new Global Emotes that weren't in the old API should be available now
Added separate Smilies (as in

etc.) setting to select which set should be
displayed locally (since this isn't handled well in the new API), the
setting is automatically set based on the old API as long as it's available
Added Local Emotes setting
Allows you to manually configure Emotes that should always be displayed
in your local client as usable by you, for Emotes that are not available
through the API
As long as the old API is available, some Emotes available through that but
not through the new API can be marked as "endangered" in the Emotes Dialog
Added follower count to User Dialog again (previously removed due to being
slightly more difficult to implement with the new API)
Other:
Tab Info Settings: Added custom color setting affecting color related options
Added setting to close tabs with middle mouse button
Added prefix config:!blacklist to circumvent the Highlight/Ignore blacklist
Updated Emoji (Twemoji set)
Updated help
Bugfixes:
Added workaround for online/offline spam in followed channels doing a rerun
