I totally agree with this, seems like I waste a lot more time on the UM3 than I do on my UM2. A lot of this has to do with the print cores. They are heating up/cooling down all the time and it takes forever. I noticed I can't even abort a print and restart it without waiting a couple minutes. All that time adds up, but honestly I think it's probably so that people who don't know what they are doing will have less of a time troubleshooting the machine.
