Right, image printing would be useful: Save as bitmap files in high resolution
Restart is indeed not yet supported in PrePoMax but it’s quite specifically defined (especially in CalculiX where files have to be renamed) and even in the case of Abaqus we prefer to define it with keywords.
*TRANSFORM is already available as local coordinate systems (they have to be selected for BCs/loads to work).
Mass elements are already available as mass sections.
Boolean operations on sets (like in Abaqus) would indeed be nice.
