First of all, I'd like to say that you're doing great product, I'm using it with pleasure.
But there is one feature which I really expect:
In PDF standard there are some accessible features, like as paragraphs, sheets and other tags. This tags have no influence on the presentation of PDF on big screens (i.e. screen of desktop computer), but they are essential as soon as you want to view PDF on small screen (i.e. PDA's one).
I'd like to see this feature in future releases of your software.
Thanks for great job,
