Re: drawing mode toggle and .dhs file type
I spent some time experimenting following your suggestion and now it makes sense. Thank you.
I would just add the following: To save a multi-shape image in-progress, save as DHS. To return to the project, reload the DHS. Continue making changes and saving/reloading DHS as needed. When complete, select all shapes, imprint, and save as .jpg or other standard file type. (This last step can be performed at any time without affecting the DHS file which allows you to check your work - just don't save the DHS after imprinting.)
It also helps to understand how Drawing Mode works with separate objects. One can get the hang of it after a bit of experimentation.
Hypersnap has come a long way over the years - kudos to the developer(s) !
