P: Select and drag photos everywhere except the mobile and ipad apps

Oh great thanks. It works but still very unintuitive as on the desktop you can just drag and draw directly. You can also drag and deal between albums which doesnt seem to be possible on mobile. 

Hello @danielkatz,

There is an option to custom-order an album on Lr mobile by drag-n-drop. To do so, select an album, and while in the album grid, select (...) menu on the top right > Sort By > Custom and tap Edit button next to Custom sort order option.

On the blue "Reorder Photos" screen, you could select photos you'd like to re-arrage and then drag them to a different location in the grid to custom re-order your photos.

I hope this helps.

Thank you,

Elmira
