Pool autoswitching sounds good, but if you can do it without the frequent disconnects resulting from the autoswitch like the other autoswitching pools, it'd be awesome.
Pool switching from the mobile page is good too, if possible you can add the current profitability of the coins to be displayed there as well as the desktop version.

 Maybe you can let the user decide on which coins can be activated/enabled on the autoswitching...   

APAC server would be great for me. 

More coins.. I don't know, not easy to gain hashrates which makes the pool attractive.
