[Start heating bed and extruder and level bed at the same time]

I have noticed the same problem. I thought it was made this way due to the fact that it takes much more time to heat the bed than the extruder and if started at one time the nozzle will stand hot and ooze.

[Feature Request]

Please add brim for supports only (not the model and the supports). I am waiting for that feature for more than a year. It looks obvious that it is not the model but the supports that fail so often and one have to design custom supports only because automatic don't stick well enough and you don't want to cut off the brim from the big complicated model just because of the one little support that needed extra stick.
