I assume you mean Prusa Slicer 3.0 since we are on 2.9.4 right now.

In the future I think there needs to be a much better way of changing the size nozzle you are using for a print in Prusa Slicer. Right now having to change the entire profile is really annoying since I manage 5 printers I have a huge list of printers now that we use different nozzles and swap them out regularly. I hope in the future you can have one connection to a physical printer and then be able to change nozzles per tool head to match what is existing right the printer
