Slack use for theater

Hi,

I am interested in hearing how many of you use Slack as a communication tool for your productions. What apps/bots/integrations do you use that you find particularly useful?

For those of you who work on multiple shows at the same venue, do you tend to create a new workspace for each show, or do you have a different way of handling it? Since we have different design teams for each show, I tend to take the former approach, but I hate having to set up all the custom integrations every time we do a new production and wonder if there's a better way of working this.

Any other tips or useful insights people might have?
