We do have a feature request to be able to string together multiple projects into one with a sort of numbered multi-select option. That would allow you to select the projects in the order you want them and then create a new edit. But your feature request made me think about it differently and maybe we can come up with a more in-line way to insert a sequence.
One thing we cannot do is to nest them because we would quickly exceed the bandwidth of the iPad or iPhone if you layered on top of that nest.
I like your folder idea also. I'll add that to our list.
Ya know, the way you suggested sounds pretty intuitive as well (at least to me). Yeah I understand why nesting simply wouldn't be possible, but the multi-numbered approach could work pretty darn well it seems. Thanks for taking the time to respond. You guys are doing awesome!
