Hi,

I would like to see a way to replace a gauge completely when current value reach a specified value.

For example if the goal is to get 40 sales per week and the maximum of our gauge shows 50. When you reach 50 I want to replace the gauge with a picture or animated picture. A fire or an meme saying "You are awasome!". 
This should be possible to implement by adding some functionality to the current indicators tab in the gauge settings.

Bonus if we could take this a step further, is to replace the whole screen with a picture. A way to celebrate extrem success stories by doing something fun on our dashboards =)
