Why isn't there a Save in Pipelines?

I have found inconsistencies with pipelines with multiple steps where you add a field in a higher step, but you don't see it even after you 'refresh schema'. I've come to terms with refreshing schema at least twice before I do anything else.

I also wish there were options for editing an active, in production pipeline with version control. 

I've also seen instances where I add a step and the fields in later steps have been wiped out.
