When it comes to logging the activity of stages, there are three different possibilities (active, inactive, error only). Usually certain stages should be logged and others don't need to be logged. As you can change this staus for each state individually, for a selected group of stages or all stages at the same time, at some point in later devopment one might wonder about the logging status of all stages.
--> I propose to add a mode in the process / object studio, where all stages are colored according to their logging status. Just by a click of a button it can be (de)activated and one can easily move through the graph to investigate all status' and doesn' t have to click on each stage individually to investigateits status.
