I would love if there was an option to pin a "message" to the top of chat.
For example, If there was a change in schedule one day and some users don't use twitter, I can pin a message to the top of chat so when they come to my stream they can see the highlighted message.
Or a big announcement that has happened you can pin to the top, etc. etc.
As a streamer myself I believe this option would be very beneficial. Channel owners and mods if given permission would be the only ones that could use the pin function. Now for Partners "Pins" would sit between " -game/currency here- Support -partnername- and the chat.
This is a good idea! :)
