I agree, totally.
The swiping is very bad as well. There is no continuous way of flipping through pages, It's only one page at a time. I have to wait for the flipping animation to finish before trying to flip to thenext page.
In general, the software needs a lot of work. If Adobe does not get on this, the AppWorld store will see more fully featured PDF viewers available for download.
On a positive note, it's great to see that the reader is only 3Mb, as opposed to the bloated 80Mb+ desktop counterpart.
