Support for altered guitar tunings...

[GodZoo]

This might be a wild fantasy but what would make this app beyond perfect for me would be if the guitar chord chart/diagram/construction option would support altered tunings (in particular Perfect 4th tuning) which I converted
to a year ago after roughly 20 years of standard tuning and regret never having done this from the very beginning. I will also be switching to a 7 string very shortly too but I suspect that's just asking for trouble.

More and more guitarists (especially the ore innovative and exciting ones) are branching out with wildly altered tunings and 7, 8, 9 and even 10 string guitars and this I think is beginning to render the old standard chord diagram and voicing books/apps somewhat limited and redundant.

Thoughts anyone?
