In good fashion, before registration starts, I delievered YACS 1.0. And as the author of a version 1.0 product, it suffers the same product-embarrassment. Ironically, that's a good thing. A couple features I could name off the top of my head as good milestones for version 2.0:

• Time filtering - To exclude schedules that have sections in specific times (e.g. "I don't want morning classes")
• Improved Scheduling View - Viewing schedules one at a time is definitely not optimal.

Those would be the two primary features for 2.0, everything else would be secondary. Also, I intend to create screencasts (or a series of written tutorials) about how I designed, developed, and created YACS. It would cover a variety of topics around programming that aren't normally covered in classes: version control, development tools and environments, deploying, design, usability, and programming tricks. It will provide a great insight to how and why code was written. 

It's a bright future. I'll see you at version 2.0
