Do actual auto-detection of DOS-order versus ProDOS-order.
...
The basic approach is just to see if GS/OS can understand the disk (i.e. if a VolumeGS call succeeds), and if not switch the order. We currently start with ProDOS order, then switch to DOS order if necessary. This is only currently done for 140k images.

Add support for image format selection and detection.
...
At the moment, the auto-detection of DOS vs. ProDOS order is just based on the size of the image (i.e. 5.25" images are DOS-order, anything else is ProDOS-order).

Support DOS-order sector data in images.
...
Currently, this is only enabled for 2mg images where the header specifies DOS order.

Report a disk switch if the length of the file changed.
...
Currently, the logic for this doesn't re-detect the file type, and it may not work correctly with some 2mg files, but it should work in most cases.

Add wrappers for GS/OS system service calls, and call SET_DISKSW on mount.
...
I think there should still be some disk-switched logic elsewhere, based on the somewhat complicated rules for it in the documentation, but at least this provides a notification when a new disk is mounted.

Report our devices as "MFM drives" so that Finder shows a 3.5" floppy icon.
...
Previously, we had actually been (erroneously) using the code for a generic hard drive, rather than a generic floppy as intended. The generic floppy code shows a 5.25" floppy icon, which seems less appropriate, so now we use the same code as 3.5" SuperDrives instead.
