So I don't know if this is in the pipeline and have seen there's a thread from Jan 5th 2015 entitled 'iOS Rig Manager' which (not sure if it's in Feature Requests or not...) I will check out momentarily... buuuuuuut.... Would be pretty handy having iOS and Android versions of RigManager (apps would be ideal!)
EDIT: wireless connectivity would obviously be awesome in conjunction - ie. A Bluetooth USB dongle perhaps...?
but can you do drag&drop with touchscreen?
