Concerning metadata management, that would be my “wish list”:
-The ability to discard/keep metadata and GPS information at export,
-A bigger Description field or to add a Notes field with more space.
-The ability to change the date/hour/min of pictures (when importing events pictures from more than 1 camera and forgot to sync beforehand).
-I dont know if necessary, but to be able to choose (with presets? config file?) which metadata is displayed in the metadata window.
And not directly related, but would complement (I know there is already a issue in redmine for that): To be able to sync a folder content in darktable from the hard drive. For now, the only way to do it is to remove the folder and re-add the folder in darktable.
