On XF 1.5, Resource Manager did display the size of the download - this does not seem to be the case on XF 2 (at least it is not being displayed here).
This has been intentionally removed. It's not overly helpful, there isn't really a great space for it with how our styling works, and it doesn't make sense when a resource has multiple files. (Oooh, sneaky reveal of a new feature! )
It was interesting information for me, somewhat like a bloat filter (eg. if a simple Add-on hat a large size I usually didn't even consider downloading).
Maybe you guys can find a great new place do display filesizes in the future
