The "Next/Last Page" bug has been addressed. And I also took the opportunity to add some toast messages to inform you when you try to go beyond the last page or to page zero (now why would you do that?). But the biggest improvement in version 1.7 (release 2) is that filters are now launched correctly from the projects page. I also lowered the min SDK (Android API) to Froyo so that more devices can use SifterReader.
SifterReader can be downloaded from the Android Market. I hope you find it usefull!
