I think it's now here :) in this section

Seems like they also deleted some embarrasings threads where they where promising stuff like Library view.... Shameful

Never saw them promise anything like this. Saw them say they are not against the idea and would look into etc but I find it hard to believe you saw this as Serato never promises features before they are publicly announced via beta or other formal announcement etc.

most likely serato remote sales were not great so it's been thrown to the wayside

The Serato forums have been condensed and tidied up.

You can find more information and the location of old posts here - support.serato.com

Maybe the sales were not good because there were no improvements and the remote was more or less useless... - why to use the remote when you still must have the computer few cm beside to fully control all the aspects of the application??
Kinda chicken / egg problem....

I don't think they could ever add all the features but they def could add more.

Just give us a library view & I'll be happy.

A MUST imo.
