- The background selection palette now includes a slider to change the size of the background grid. Default min/max values are 16 and 64px, defined in UBSettings. Grid resizes dynamically as the slider is moved. - Measuring tools' (ruler, triangle) markers follow grid size: 1 square of the background grid corresponds to 1cm - Grid size can be different for each page of a document - Grid size is saved in the .svg - Documents with a background grid but no specified grid size follow the default size defined in UBSettings. Previously, grid size was calculated based on DPI, which can vary from one OS, computer or display to the next. This new setting allows documents to be migrated from one machine to another with no unexpected changes in grid size happening. It also makes it easy to correct any problems importing old documents (whose grid size might be smaller or larger than expected when imported on a new version of OpenBoard).preferencesAboutTextFull
