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.
