suggest two features Export only missing tracks. Show only tracks not exported to this device

I would like to suggest two features that would significantly improve playlist management between rekordbox and USB devices.

1. Synchronize playlist order from USB back to rekordbox

It should be possible to transfer only the track order from a playlist on a USB device back to the corresponding playlist in rekordbox.

Sometimes DJs change the order of tracks directly on DJ equipment or while working with a USB device. After arranging the playlist on the device, there is currently no simple way to apply that same order to the original playlist on the computer.

The ideal function would:

• recognize that the playlist on the USB and the playlist in rekordbox are the same playlist;
• copy only the custom track order from the USB back to rekordbox;
• keep all existing tracks and playlist data;
• avoid replacing, recreating, or fully rewriting the playlist;
• optionally ask which version of the order should be used if both playlists were changed.

For example, there could be an option such as:

“Apply USB playlist order to rekordbox”

This would be especially useful for DJs who prepare or adjust their sets directly on CDJ/XDJ equipment.

2. Compare playlists and clearly show tracks missing from the USB

It should also be possible to compare a playlist in rekordbox with the corresponding playlist on a USB device.

Rekordbox should clearly highlight tracks that are present in the computer playlist but are not yet on the USB device. These tracks could be shown in a different color, with an icon, or through a dedicated filter.

For example:

• On USB
• Not on USB
• Modified since last export
• Missing file
• Unsupported for export

There should also be an option such as:

“Show only tracks not exported to this device”

This is very important when 20–30 new tracks are added to an existing playlist. They may be mixed throughout the playlist rather than added at the end, making it extremely difficult to determine which tracks have already been exported and which ones are still missing.

It would also be useful to have a button such as:

“Export only missing tracks”

without replacing the playlist order that already exists on the USB device.

At the moment, managing two versions of the same playlist is unnecessarily complicated and creates a risk of losing carefully prepared track order. These features would make rekordbox much more convenient and reliable for DJs who regularly update USB playlists.

Thank you for considering these improvements.
