my feature requests :)

Hi I have a few freature request.

1. pls show key of the song somewhere in the beginning of the playing screen? At the moment there is a dropdown for selecting instrument, and a transpose button. Maybe make space to show the key here? I do not think I need to explain this becasue the key to a song is very important. 

2. allow users to select the prefered inversions to display for each chord - can go in the settings. I say 80% of the time I use the suggested chord diagram (piano). Time to learn other inversions and the chrod diagram is so critical for learning and is one of the best features of chordify for me. 

3. from my playlist is it possible to summarise the top 10 - 15 most used chords?

   a. Good for focus practice becasue these are the most used obviously. 

   b. Good info to choose which chords to practice more inversions

   c. target these chords to learn runs on becasue we use it most often!   

Thanks again to the Chordify Team for the great app!
