Adobe Reader is a very unintuitive software and a pain to use. The most accessible buttons are often the most seldom used, and the needed ones (boomarks, sticky notes) require to pull out a drawer which ruins screen space. I'm currently learning to use Blender, have Blender open to the left, Adobe Reader to the right, and Adobe Reader is a pain you know where. If Apple designed a reader you'd probably have half a dozen of buttons in a slender title bar, and that's it. Adobe Reader looks like a clunky Windows application. Is there an alternative to Adobe Reader?
