Process Tree View #10

It would be really cool to have a process tree that's sorted by which processes are exerting the most memory pressure.

hi @kennbr34 - sorry for the long time delay and I just got a chance to look into this feature this weekend. i created a new version 1.4.0 to add process tree information in reverse order. i feel like if we sorted the process via memory usage might be a bit confusing so i left the process tree in the normal order.

the process tree information part includes the following information:

Example output:
