Hi,
the last view weeks I work intensively with MCG to learn it. Sometimes I find it very difficult to find out where I made a mistake. The feedback I get in the Message Log and the colored connection lines between the nodes are often very vague especially in a bigger and more complex flow. I used the trace and print nodes, but if you want to trace several information at the same time, the output in the script listener is very chaotic and it can be hard to keep the overview. It's better after I created a compound which combined the print node or trace node with an output of an string to give the arrays and numbers a name. Still, the general information about where or why a problem happens is not very helpful in a lot of situations.
I would be grateful if you find a improvement for this.
