lightroom on the iPad is severely limited. Can’t merge panoramas (a feature I use all the time, I shoot a lot of Panos), no ability to use certain plugins like those used for certain photo printers, limited import and organization options, support for external drives and network storage, you name it.
Lightroom for iOS is absolutely fantastic, but it is missing features that are dealbreakers for me and my workflow. But if I could run the full desktop version of Lightroom, then my M1 iPad Pro (whenever it arrives) would basically become my computer.
