There are a few features I would love to see in the future:
1) the ability set the network configuration via the web interface (in case I need a static IP).
I only have so many hours in the day

. It is on my list though but there are so many other things that need doing/testing.
2) the ability to backup/restore settings and the charts.
Once I get live update working I will be sticking all the settings into a sqlite DB, it will make for easy backups and restores from the WebUI.
Also, what files do I need to backup to save the charts right now? I might need to re-write my SD card soon.
You need to grab;-
miner.conf miner.conf.donate miner.conf.tmp timezone uipassword version
From;-
/opt/minepeon/etc/
AND
/opt/minepeon/var/rrd/* (that is where the graph data lives)
Practice this now! I am just uploading a new urgent fix release.
