Suggest Existing Commands
I know many Streamers have Nightbot or other similar services connected to their Stream Chat, but most new users don't know all the possible commands they could use.
One existing solution is that users can type "!commands", but then they are just linked to an external website to see all available commands.
I propose a better solution where once the user types the "!" character, they are given suggestions with commands already existing in the Nightbot.
For example, in TeePee's channel, if you type "!", you should be given suggestions for "!sens", "!triggers", "!loadout", etc, similar to the auto-complete feature available on Google searches.
I believe this would lead to a more user-friendly experience and keep users on the Twitch website rather than going to Nightbot's website.
