Lost numerous local files on my iPad with comments and highlights in the "downgrade" process.
Readle also took away options of swiping top to bottom instead of left to right and the option of having tabs at the bottom of the interface - which is how I preferred to use this software in the last edition.
Version 4 was perfect. This app is a total downgrade, waste of money, and managed to lose data I was depending on.
