I have mostly large computer books on my kindle. this update is a disaster as the new go to works poorly with the table of contents. whereas it the past I could go to a chapter, then a subsection, now some books only list by subsection with no reference to chapter and some now just have chapters and no subsection.
Since I cannot navigate large books this way, if amazon does not fix this I will request that every book I purchased since getting the touch be refunded.
for little old regular paperbacks I am sure this go to was an improvement but it really broke things for me.
