EDIT: Just thought what about a mobile interface?
curious, what kind of mobile interface are you thinking of? the current web UI scaling well in a mobile browser? an android app? an iphone/ipad app?
More towards smartphones etc nothing really detailed, stuff like the basic miner details etc. More for those who's PC is either being used or something along them lines, or even if they just can't be bothered to turn the PC on.
EDIT: Another suggestion (Which might be in the works) is having a set of graphs for the RPi information. Maybe have a seperate tab for it, as I sure that a fair few people would like to know what/how their RPi's are handling it.
) is being introduced as a proper application frame work and it has mobile extensions.
Backups and restores are also coming up in the next versions as well as better process management of the miners.
