S L O W
I used to like it, except for the awkward sorting order. This is now better, though you need to be at the top of the page to choose your sorting method (when there are many scores this is annoying).
In previous update it froze on start. This update (3.0.1) is so slow that I rather use Adobe or iPad iBooks.
Life is too short...Hope developers sort out this issue.
Update:
With the current update of today (3.0.2), it is even S. L. O. W. E. R.......
Currently, useless for me.
