File access on a file basis instead of block device level would be the 
next "bit of refactoring".

Furthermore, sd2iec uses X:FILENAME to access different partitions 'X' 
on a SD card just like the CMD hard disks used making the usage of dual 
drive code (very common in the CBM/PET world) very hard since it 
requires to hold disk images for different drives on different partitions.

Unfortunately, I haven't been able to convince Ingo of the need for a 
"mount/assign" command to get rid of the current handling focusing only 
on partitions.

Last but not least, it seems to me as if it is not that easy to add code 
to the sd2iec repository. There's a patch for the usage of a LCD display 
without the need of a second MCU made by somebody else that never went 
into the main code base as well as my support for D80/D82 disk images 
never did.

sd2iec's fastloader code assumes the AVR running at 8 MHz which isn't 
true for the XS-1541 so that code would have to get re-worked anyway and 
REL file support inside disk images simply does not exist.
