It would be extremely helpful to have a "Cancel" option for bulk uploads. I just pushed 1200 items to ebay by mistake and I have no way to stop the process. It is taking forever to complete and I can't attempt to fix it until it does. A cancel option would be very helpful in these situations.
I agree and would also like to see a "cancel" button on bulk exports and uploads. The few times it is needed will save the headache it creates for support having to be contacted.
I suggested this last year. The only way I have to stop these mistakes is to contact Surdone and have a developer kill the running process. Since I am usually updating 60,000 products at a time, it would certainly help to stop those processes on the fly.
