Ape Apps

Hello. I know there is an all workers button, however, when i tap it none of my workers appear. I dont know why but thats not my point. I was thinking it would be cool to have a Colonists Management button. So you can select your colonists without having to hunt them down to rename them or change their jobs. I dont know if thats what the all workers button does or not because, again, it isnt working for me. Basically you can do every thing you can do by tapping/clicking on the colonist without having to hunt each individual one down. If this is what the all workers button does please tell me
