Many times I find myself wanting to run essentially the same job with slightly different parameters. This may be on a per case basis, or it may be a large batch of jobs I'm running as a grid search. To do this, I usually have my tables configured in a way that each experiment/config is one row.
When arrays are involved this becomes a bit tedious because the existing copy-paste functionality doesn't actually work as expected. There's no way to click the Copy icon and then directly paste an entire array into an empty cell. The array editing GUI is essentially unusable for anything more than a few elements.
A couple solutions that would make life a lot easier:
1) a "duplicate row" function
2) a copy-paste functionality for individual cells that contain arrays
I totally understand that you don't want to reinvent Excel in-browser but I think these additions would save a lot of export-edit-save-import cycles.
