Based on original pdfviewer by James Milne and NerveGas ,improved with a couple of features...

Improvements :

• Now supports navigation by page number
• Supports landscape. (IMPROVED in 0.3)
• Integration with mobile finder (Double tap on PDF files would open them with Solena)
• Remembers most recently used PDF settings (open last pdf file from last page number,offset and zoom)
• Remembers all previously opened PDF settings.(NEW in 0.3)
• Supports opening of large files
• Some little improvements ;)

Known issues :

• Not as smooth and shiny as Safari PDF Engine (zoom and pan features aren't smooth).
• Removed 3 page algorithm by Milne (so zoom and pan looks even worse but works flawlessly).

To Do:

• Remember last time settings for all opened files (not just the most recently used one). (NEW in 0.3)
• A mechanism for opening finder inside Solena when user wants to open another PDF. (NEW in 0.3)
• Support bookmarking.
• Some UI enhancement.
• Making installer friendly package.

Instructions

• Make sure you have MobileFinder installed before doing this.
• Download and extract the zip archive and put Solena.app in /Applications on your iphone(ipod touch).
• Grant execute (755) to Solena
• Put the following line on the file association section of MobileFinder settings pdf:com.dpasdar.projects.Solena (OPTIONAL in 0.3, only if you want double tapping to work inside mobile finder)
• PLEASE NOTE THAT format of settings has changed since 0.1,so please remove com.dpasdar.projects.Solena.plist from your Preferences directory (/var/mobile/Library/Preferences) before updating to 0.3.
