It’d be nice to be able to batch copy several cells from one notebook to another existing notebook. If you’ve already created a notebook but you want most of the contents from another notebook you can no longer fork it.
Some kind of batch copy or partial fork into an existing notebook would save a ton of time.
I would like to be able to fork individual cells. I sometimes think an import can be a bit heavy weight or include more than unnecessary, so I tend to just copy and paste small snippets but then the provenance is lost.
