Not sure if you're still maintaining this, but I tried importing a few scripts from another project, but for some reason it spat out the scripts that were living in a nested folder into the root of the Script list instead of actually putting them into a subfolder. (Also it took more than a minute to transfer 36 files, but I'm not sure if my destination project being relatively huge has anything to do with that.)

Still, this was much nicer than transferring everything manually. Thank you!
