Description
PATH and CMDs would be great for this to save time and mental overhead for saving graphics. Also, there are GR memory-hole related issues that prevent simple loads and saves. I'm considering building this one out myself, the HGR would be a wrapper around the BSAVE X, A$2000, L$2000 command. GR and DDHGR would be more challenging.
There could be a single command (GSAVE {GR|HGR|DHGR} <filename>) or multiple commands (GRSAVE, HGRSAVE, DHGRSAVE) that would be shorter and simpler.
A viewing command would be very handy for browsing - I found a ton of value in the TYPE command being able to dump BIN files- a nice touch! This would be the visual verison of that, a "view-all" swiss army knife.
VIEW <filename> would detect the starting address of the file, and load the graphic accordingly based on the starting address.

Research direction
Start by reviewing the existing PATH commands and the TYPE command's BIN handling. Define the command interface and behavior for saving and loading GR, HGR, and DHGR pages, including the stated memory-hole constraints; a VIEW command would be complete when it can select the graphic mode from a file's starting address.
