Add more information to the calibration results window like: touch speed, scan speed, move speed, prehit/retract distance and so on. It would help to decide if the calibration has to be done again because of differences in these settings.

Here's an example:

Add something like a clearance cube around a probe changer if desired.

Basically like a saftey zone around the rack so that someone cant run probe, probe head, z rail into it while running a program.

Add a field in the lower level matrix calibration dialog box which informs the technician when the last time the lower matrix cal was performed.

When scrolling through a large program it can be difficult to find where you are in the program, even when clicking through bookmarks.

Colour coded markers on the scrollbar might help find bookmarks/breakpoints etc.

Some drawings show a gradual transition between profile tolerances but I'm currently unable to show this in a CMM report.

Add the ability to work with Wind Chill cad management.   At least around here, Team Center is dying. 

Found the constraint on radius/diameter of Circle, but need the constraint activated on the center of circle, to calculate actual radius/diameter on very small portion of circle.

When reporting features to Datums with MMC, the position of the features measured tend to always be zero, while the Datums the features are referenced to have a measurement? why is this? can the datums not be removed so only the features being measured show a measured value.

After Collision Detection has been run have only the Feature ID's on the Collision List appear on the Graphics Display Window.    This will cut down the amount of searching for a feature that occurs.  

Better yet, have collision detection automatically run as you offline program.
