Just okay app but I did not uninstall Adobe.

Pros: fast rendering and nice full screen mode. Adobe sucks. Books organisation. Tabs.
Cons: Navigation and toolbars. I feel it more convenient in Adobe.
Lack of feature: Many manuals (car repair ones) are distributed as many PDF files. Each PDF file corresponds to the particular section or even single page. All if them are kept in a directory structure and linked to each other. You navigate from file to file by clicking links. Clearview does not open another file by link. Adode does. Add this feature and I will re-rate the app. You can contact me for thorough description by e-mail (nDOOTloshchininATTTgmailDOOTcom).
