I use expensive block accounts as fill servers to guarantee 100% completion, no matter what it is, no matter when it was.
Prior to this regression, I could quickly glance at the download list and see what server colour was being used.
If my block servers were getting hammered (i.e. 100% use), I'd look for options if the download was 7 days new, or clap if it was 7000 days old.
Unfortunately, in RC3, the colours have been disabled! Yes, I know I can have the server window open instead, but then I can't see what's being downloaded in the queue without manually flicking back and forth.
Observing server usage from the download list is a REQUIRED feature for anyone using limited quota servers, in particular for those filling in with paid block accounts.
