A few small suggestions
- the ability to customise the name of custom sets. iow change the C1, C2 labels
- in addition to the often mentioned increase in bracketed images, to identify them in the filename e.g DSC0034-1, DSC0034-2
- Allow the user to identify which bracketing option was used e.g. in an IPTC field
- the ability to set IPTC data of photo's when shooting them. e.g. location, job nr, ...
- the ability to backup and restore camera configs and/or allowing them to sync across bodies
