New features:

Add Delete and Move functions to scene browser name menu. Delete allows you to delete the targeted object, group, or style without needing to set selection and Move can be used to transfer an object or group to another group or to rearrange styles from inside the Scene Browser.

Update point picker in Polyline command to allow angle values relative to the previous line segment.
You can now type in polar coordinate values like this:
   5r45
   9L20
The polar distance is first, then a lower case or upper case L or R followed by the angle in degrees.
This will control one of 4 angles either to the left or right (L or R) side and uppercase L or R will control the outside angle while using a lowercase letter will control the inside angle.
You can also enter in just an angle constraint with no distance value, this will create a tracking line to the left or right of the last drawn segment.
R20 will make a tracking line at a 20 degree angle on the outside from the last line segment.
r20 makes it at a 20 degree angle on the inside.
L20 or l20 does it on the left.

Add Zoom option for 2D drawing (PDF/AI/SVG) output for "Fit to page" mode. You can put Zoom: 95% for example to shrink the drawing towards the page center and have more padding around it.

Add new option for view rotation behavior under Options > View > Rotate/Pan/Zoom options > "Rotation style = Rotate around CPlane z axis".

Add option for Annotation arrow type = "None".

Add support for tags/keywords file properties on Windows.

Add option to use viewport background color for PDF/AI/SVG 2D output so it can look more like a screenshot. Currently to turn it on it’s a setting in moi.ini, in the [AI/PDF Export] section, set
