What happened to this app?

Ive been useing puffin since version 4 and that had more features and themes, the app has had a serious downgrade in my opinion, and its recently on some sites messed up certain scrolling features like arrows, and the search engine bug will default to bing reasonlessly. Lots of people miss the old version it crashed less, and lagged less too, do yall even read the reviews? The flash support is the only reason I still use this and the speed. If the other interface was in the pro-version that would be great.
