I too liked the estimated pay per block for the two main reasons given: 1) I used it as a single-number indicator of how my equipment and the pool were doing - if it changed much, I looked into why, and 2) I used it as an indicator of how many more blocks needed to be found to reach my auto payout setting. I would vote to have it as an option to turn it on. To be honest, I don't understand how it led to any problems. I am also convinced that whatever you change it to (like the current pay/Hour stat on the shifts page) there is still going to be a group of people who don't understand it or are bothered by what it shows (such as "unpaid" shifts). I believe it is impossible to please everyone in this situation: there will always be people who don't think they are being paid enough or have unpaid shifts or

Too many people just don't understand that finding a block is a random event and all the stats in the world won't change that.
I like the suggestion of a graph of my recent hashing history as that would be another good way to check on my equipment over the medium term (perhaps 10 or 20 shifts). Seeing my current hashing power without having to bring up a stats page would be good too. On that note, having the pool hash rate being the first thing that comes up when using the "Live Stats Pop Up" seems redundant since it is on the top of every page including the one I just clicked on the link from. A more useful first page would be either the "Me" or "Round" tab, both of which contain my current hashing power.
I generally always leave the "Blocks" page open and refresh it whenever it occurs to me to do so. This is a simple way to see if new blocks have been found and to watch the confirmations count down for found blocks. It would be nice if this page had the current UTC time, or even better, the current length of the current round (or best of all, both).
I suppose the "Live Stats, full size" contains everything I want (except the number of confirmations on recent blocks), but the layout means what I am looking for requires scrolling. I'd like the "Current Round", "Latest Blocks", and "Latest Shifts" side by side without anything else as I'm either not interested (Fastest Users) or it is already shown in the Current Round (Total Comp. Power, Your Comp. Power, Workers).
As someone else suggested, maybe a customizable layout is the only way to satisfy everyone.
Overall though, things are good and the pool runs well which is what really matters. Thanks for your effort to always improve things.
