Ability to upload to multiple galleries at once
For some of us who have to carve out a day or two per week just to edit, it would be so nice to be able to create, and then upload to a couple/to a few galleries at once, rather than one at a time.....
This would help so many of us knock stuff out so much quicker!
Upload different galleries in different windows or tabs at the same time.
I do this all the time with no worries, yet I don't do it directly from Lightroom (It's faster to not do it from LR anyway)
I'm pretty sure you can do this from Lightroom using the Pixieset Plugin. i.e. create different Collections and sub-collections drag your images in Lightroom hit publish and walk away.
