Collapse plots list, group by harddrive

[preto677]

Would be cool to have a possiblity to group the plots by the drive and collapse each drive independendly.
Right now its possible to collapse entire harvester, but imo would be useful to group it by harddrive as well.

Few months ago I've found out, that I had like 40 duplicates (out of few thousands plots, no idea how it happend but, well..)
and I had to play a bit with cli to find where they are, I managed to do that rather smoothly, but it would be faster if i could see that in the gui.. lets say, click button "collapse all Hdrives" and on the header of each of them we would see hdrive name/label, path, size of plots, number of total plots and number of duplicates.

Wdyt? :)
