Why did they drop the Orientation Lock feature?

Ive been a big fan of the Bluefire Reader since it initially launched because of the extra features like Orientation Lock. This latest upgrade dropped the Orientation Lock feature and I already miss it. I find it very frustrating to have to adjust my reading position to suit the iPad. I hope they restate this feature soon or Ill have to find a different reading app.
