I totally agree, in fact feature number one is already planned. It'll probably be in the form of a chord schema generator and player that also shows you which scales and roots/thirds... you can use in a given chord.
For 2, it's possible to flip the fretboard to a lefty guitar. Is that what you are looking for? You can find the option under settings. Or do you mean flipping it vertically?
Oh right! I see what you mean. Got it, awesomeme idea: Chord charts like these are as of now a planned feature. Something to look out for in the future.
