First I have to say, ModularGrid is such an indispensable site! I would have been completely lost and probably never had the nerve to jump into modular without it. I was happy to contribute by buying a Unicorn account.
My feature request is the ability to create module profiles/images that are not public. I have a few unique aspects to my rig that I'd love to be able to add to my personal rack but I feel will only cause confusion if they show in searches. Specifically, I've made a sort of breakout panel for my Kenton Pro 4 to make the outputs directly patchable within my rig. Additionally I have my Beatstep Pro mounted in a row. I know it's not 100% necessary to see this while arranging my modules but the visual sure would help.
It would also be nice to be able to select multiple modules at once to move as a group. Like dragging a selection over a group or something like that.
I don't know if either of these topics have already been addressed so sorry if they have.
Keep up the great work!
