This addon seems to lack any basic usability? the UI elements are basically all there (and are very sleek), but there doesn't seem to be any kind of 'add stream by url' feature, editing the streams of the two devs the addon comes packed with to have different url's didn't work either, and the search function despite looking like it should work, doesn't actually do any searching, simply staying blank when you hit enter. Does this addon not work at all or am i just dumb?

Edit: Thanks so much for your quick response! An explanation of how to add streams should certainly be on the description of this addon and probably on the 'help' screen in the addon's options as well... additionally, (and this is a pretty small nitpick buuut) regardless of the chosen theme the fade-in effect when opening the addon uses the defualt bright blue, which is kind of eye-searing when I've chosen the dark theme.

The app works perfecly fine, looks sleek and professional, and all with a fun level of customization with the themes and notification sounds.
5 stars, great for anyone who once had the Livestream Notifier by Freaktechnik, which sadly seems to no longer work with twitch.
