Hah, This is the first time I hears about Foreman (been away from Rails for 1.5 years), but I'm so glad to see process management for development has gotten fixed! In the past, I even wrote an OS X application for managing the running processes, watching stdout, etc. - but as homemade things go, it never was 100% perfect, kept dropping state, forgot how to scroll nicely (one of the problems you face there is that you end up reimplementing a tty).
Foreman seems quite smart, as complete as (if not better than) my old app - and it's configurable, too! Goodbye Soupsie.app, hello foreman (-:
