When we configure object activities, sometimes Mendix, or ourselves, put in xpath definitions to control what the object activity retrieves.
Much like the CSS button in the page viewer, can you add an XPath button in the Domain Viewer? If we click on it, Mendix pops up (in tooltips or annotations) the XPath statements that are present. The setting should behave like a pin, we click it in, it shows the xpaths, and they remain, we click it again, the tooltips/annotations disappear.
This would help significantly in figuring out what is going on in a flow, and we lose less time in development by having to manually add static annotations, or maintain those in cases of changes, during development.
