I'm trying not to ramble on this one. I'd essentially like the ability to choose between the two UIs... Perhaps via a registry setting, or something similar. Here's what I don't like about the new UI: 1) It's pretty big. Not sure why it needs to use up 1/4 of an HD display with a lot of wasted whitespace and oversized fonts. 2) It hides all the details we geeks like to see by default. 3) Resizing columns is buggy. 4) I'm not a big fan of the circular progress bars. Would rather have an actual bar, or just a number as an option. 5) The UI can no longer be read by screen readers for accessibility. This prevents one of my good friends from using it. Here's what I like about the new UI: 1) I like the introduction of the ETA, but it is really, really inaccurate. You probably need to do a median filter on the results of this one. 2) I like the colours and the flattened style. But otherwise I love sync. I use it to manage deployments across several data centres and home for synchronising media across tablets and my media server , and it all (mostly) just works. Just slightly disappointed in the last revision. Cheers, Soen
