To get around the case folding issue you could mount your steamapps/common folder as a loop device with ext4 with case folding support. The virtual device should follow the compression settings without too much issue but deduplication won’t be an option and snapshots may be larger.
Seamless docking would be ideal, but I’d hate to have to use a proprietary POGO connection. Just fixing the proprietary dock so I don’t have to power cycle it so often would also be nice :/
