Many thanks for the feedback after publishing Version 184.108.40.206. This new version contains bug fixes (thanks KdP & CG), a long outstanding oversight (thank PS), and small improvements:
The markers column values were accidentally limited to 0 to 100 and corrected.
Large marker datasets previously loaded slowly and was corrected.
The layers grid can now be sorted by clicking on the header columns.
Multiple measurements can be made as either lines or cylinders and saved as a DXF-file with the layer names indicating each segment length.
Measurement lines are not automatically deleted any longer, as users wanted the ability to accumulate multiple measurements to save. Delete the measurement lines/cylinders with the "Delete measurements" option in the same toolbar dropdown button as creating the measurements.
Improvements to the scalar bars formatting for meshes and markers.
