Hi,
The more I become familiar with the workflow in Revo Metro, one “issue” in particular stands out:
When navigating using CTRL + Left Click (e.g., while using the smoothing brush or selection tools), holding the CTRL key and using the mouse wheel to zoom results in an inverted rotation compared to standard navigation.
This inconsistency between “tool mode” and “standard navigation” is quite irritating when moving around a scanned object to clean up or smooth surfaces, as it disrupts the workflow and muscle memory.
While this may seem like a minor detail to some, it is quite taxing on muscle memory and constantly disrupts my navigation flow. 
Is there any techincal reason for the inverted zoom whilst holding CTRL?
