Old version had better functionality

I started using Mu on a recommendation. I was told it was one the fastest PDF reader. After downloading i had to agree i no longer found my self waiting for pages to catch up while i was looking through a document. I was quite content with Mu and used it for all of my ipad pdf needs. Until the update. I tried to like the update but so many of the key features i come to expect in a PDF reader seem missing or are so hard to find that i still don't know how to use them. Key features that are missing to me.
1. I can’t go to specific page number. I cannot find what i need to press to type a page number and be able to go straight to that page.
2. Bookmark drop down menu does not allow collapsing categories. This means lots of scrolling through the menu often missing what I’m looking for due to the sheer number of bookmark choices.
3. Inability to keep a file in Mu. I have several books i reference frequently saved to Mu so i don't need to transfer them with internet acess. Since the update i have been unable to add books. They show up and then when the app is closed they disappear.

I thought the load speed would make up for these missing features but it doesn’t. So in at this point it back to other PDF readers.

Very Fast PDF Reader

This is one of the fastest PDF readers I've used on iOS. There are only two things that keep it from being 5 stars for me:

1. There are touch zones to the right and left of each PDF page that move you back and forth between pages. This can sometimes get in the way and I would like to see an option to either disable it or tweak the settings so that the touch zones stay farther to the outside of the document.
2. The other thing I'd like to see is the ability to rename the PDF documents.
