Hello I was wondering if its possible to customize the bot status display or if only that 4 options are available.

Now i have it like this "Playing 5/100 players!
I want to hide that option to show only: "5/100 players!"

Thanks!

You can't do that because of Discord API as I see.

This is correct. You are able to change the ActivityType for each message, though. To do this, go to line 106

var index = GetStatusIndex();​

add below it (and read the italicized note below):

config.StatusType = StatusTypes[index];

Next, add at line 29 the list of StatusTypes you want to use that directly correspond to the order of the line items you have defined for Status in the config.
Note: You must use exactly the number of StatusTypes here as the number of Status messages defined in the config.

For example with 5 Statuses defined in the config:

        {
            "Game",
            "Listen",
            "Game",
            "Watch",
            "Watch"
        };

Note that the "Streaming" Activity Type currently only supports Twitch and YouTube URLs. If you define an entry as "Stream", your bot will still display it as "Playing".
