Is there a single location where we can go to find out what each MSG operator does and how their parameters work?
I've been trying to eliminate some rectangular artifacts from a MSG preset. (They are artifacts for me, at least. For someone else they might be a desired effect.) It was really difficult to know where to start looking in the MSG chain, so I simply started at the top and worked my way down. After an hour or so, I found an operator that had a strong influence on the effect (RGBMinMaxRangeArea). But it had a parameter that is simply labelled "Area Type". Knowing what such parameters do would allow a user to search for relevant operators more efficiently.
More detailed documentation in reference form would have been a great help to this process. The tutorials are great, as far as they go, but information on the individual operators is scattered across several tutorials, making it hard to find quickly.
