I like what cenicsoft had said as well.

For me, when I log in, I typically go to two areas... The main account page, where I would reference the "expected pay per block" and the live stats.  As I noted previously, that is a single number that gave me a snapshot of how things were going for me, relative to the pool hash rate, based on my own hash rate, over the last 10 shifts.

If it is confusing to some people, I'm not sure how; however, for me, it was very useful.  Nowadays, with big hash rates coming and going, individual miner scores may vary from shift to shift, so this gives a one number snapshot of my status.  Also, is I add or modify my equipment, I get an idea of my FUTURE earnings in Bitcoin, based on the current pool hash rate.  

Transaction history only tells me what has already happened. If we are in the middle of a difficult block, as the pool hash rate goes up and down, I have to look at my scores the latest 10 shifts to estimate that number.

If you think it should be an optional setting to bring this back, I would support that, but please reconsider bringing this value back.  

I'm still assessing as to whether the changes to shift history is useful for me. It's okay, but not thrilling for me.

As for shift length, I like the shorter shifts.  12-14 hours per shift was just getting too long...

A graphic of each miner's hash rate over the last 10 shifts would be useful with a precision of 1 minute. Where I mine for LiteCoin has that (give-me-coins) over last 24 hours and they do provide a "Round estimate" value which is similar to be expected per block!😉

Finally, something to think about might be to ultimately use responsive UI design for the website... I'm sure many of use smartphones and tablets to view stats on bitminter.com.  But I would consider that a lower priority as it does look fine on my iPhone and iPad.
