I usually prefer to save my images in folders named YYYY-MM-DD, so they are automatically sorted by date. I also like to save them with a 12 hour offset, so images shot around midnight are not split into two folders. Currently SGP provides the 12 hour offset only for the whole date in the silly form MM-DD-YYYY (%d2) or just the date number DD (%dy). Using %dy-%mm-%yy does not work, since the 12 hour offset is only applied to the day number, but not the month or the year. So if I’m out photographing on 31.12.2015, %dy-%mm-%yy will flip to 31.01.2016 after midnight.
It would be nice to either change the date format to YYYY-MM-DD instead of MM-DD-YYYY, or provide the 12 hour offset versions for the month and year also.
