I'm not a major miner, but right off the bat I'd say I prefer pools that do not require an account login, using solely the payout address as the identifier. Using message signing (could be a one-off with cookies) that can still provide access to statistics without having to make those public, should that be a concern.
I think you're using, or building upon, a pre-built pool server kit (MPOS?), so I'm not sure how familiar you are with its workings, but going through the registration progress: after I registered I'm supposed to log in - but it still shows the 'register' form. Given that there's no account verification requirement, other than for a redoubling of confirmation that the user knows their username/password, I'd think that need to log in right after registration is a superfluous.
The 'Home' link should probably go to the Dashboard page, with Home instead being News/Announcements.
I'm pretty sure the timezone detection is broken - Pacific/Wallis is at least not correct
As for features.. there's plenty..
- being able to form groups with group overview and APIs (without requiring a shared account, I think the now-defunct 50btc had this working pretty slick, triplemining did as well.)
- not needing to set up workers (not sure if actually
required, but the steps all outline the
username.workername settings so I'd imagine you should..the steps make no mention of this)
- * having per-worker miner settings easily available to be copied and pasted, including the username/password pre-filled in, to make it easier for people to get started (btcdig)
- adding the option of (semi-)randomly paying out a little more to some than to others (triplemining)
- add merge mining for e.g. namecoin (even if deemed 'worthless' it'll give people
something)
- adding the option of a solo pool (various pools, catering from those with big hash rates just not wanting to share so much to those with low hash rates playing the lottery)
- accept cgminer's --suggest-diff (ckpool) to aid vardiff with an initial value (when not using the fixed high diff ports)
I'll point a GekkoScience Compac at my test account to look at the bits currently not displaying much of anything, but I think there's very little extra to be desired from the statistics overview.
Debbie Downer mode: Thing is that until you gain some sort of critical mass, a lot of people tend to stay away from small pools due to the low block interval and thus payout interval - and you'd have to consider whether any changes requiring effort will actually bring about getting such a critical mass to be worth said effort. The features I mentioned, for example, were implemented at pools already and it didn't save them, btcdig is still pretty small as well, and even somewhat larger pools, like BTCGuild, have thrown in the towel over time.
On the up side: you're engaging people and at least considering your options.. given how few public pools remain, some of which under neglect, that's already a plus.
