can we stop and resume plot creation, or we need to do it manually by appending next nonce range?
I had my laptop close twice (thanks to my kids) and plotting resumed without me having to do anything after logging back in...I think as long as the java window and the command window were not physically closed, then it should resume. Although if a hard reboot is done than you might have to replot from whatever number it ended at (or whatever number you can deduce it ended at given the size of the plot file you have generated upon restart).
Yea, this is an annoying issue, I just started 3 2TB plots on another computer, and it's going to take quite a while... if it gets shut off for any reason I will have to manually figure out where to restart the plotting...
There should be a way to check which nonce was finished last, so that we can start from the exact correct location when these sort of things happen.
