Hi,
In general the changes look nice. One issue I've seen is that the racks are stretched too tall or something and the bottom of the racks cover up the stats (like the power usage and costs, etc) EDIT: I forgot to mention I'm using Windows 10 and Google Chrome browser on a PC laptop.
And unfortunately for me . . . one thing I've been taking advantage of for a long time is the fact that the command window used to only show 4 racks horizontally, and my main system happens to be 4 racks wide (and 4 racks tall) so I could carefully name my racks in such a way that they would line up in the same order as my physical system. Now that the Command window allows 7 racks horizontally I had to add 3 filler racks on each of the 4 rows to get my alignment back. Oh well . . . .
