I have my miner running with a config.conf file but it's not stable in the long term, so I would like to use multiminer to restart it after 6 hours.
I keep selecting LBSPHSGMiner, but nothing changes.
Also when adding coin I can only select SHA-256 or scrypt.
You can manually add ANY coin you like...just type it in the box
I have yet to switch to X11 yet, hoping I can get that done today after some maintenance.
As mstrongbow indicated you can type whatever you want when adding a coin. If it is not in the list, you will be prompted for an algorithm, including X11.
The reason you don't see more options is you have the Coin API set to CoinChoose.com. CoinChoose is the default because it is free, but it only has SHA and Scrypt algorithms. If you switch to CoinWarz you'll see more coins and algorithms when you add a new configuration.
