I would like to add a button in the UI for each stack that will launch your choice of Terminal with a session where the PATH has been set to point at the services in that stack.
I'm interested in thoughts about how to handle stacks which have multiples of the same service. For example if you have two PHPs in your stack, which one should be in the PATH? About my only idea is to use the vertical position of the services in the rack; the higher one will be in the path, subsequent ones will not.
Another idea is that this button would be with each service rather than on the stack overview. In this case it would set that service first in the PATH, followed by all other services in the stack.
Secondly, is there anyone here with enough terminal knowledge to suggest a nice way to configure the PATH when launching a Terminal? I would want it to work with any Terminal you might choose, so it can't leverage specific features of (for example) iTerm.
