I'm trying to decide whether to support multiple configurations within my application or to just support a single global configuration specified with the OCIO env var. It's relatively easy for me to support both, but it does determine where the controls go.

I noticed Mari has a button to load a config right from the OCIO bar. But the OCIO documentation recommends in practice a single global OCIO should be sufficient.

I can see that supporting multiple configs would help facilities who are transitioning from an older color workflow to OCIO, or possibly working on multiple projects, each with their own color management issues. Or am I over-thinking this?

What is the consensus on how much control I should provide?
