There are a few web design mistakes that particularly annoy me.
- moving the login / logout buttons around on the page
- disabling the back button
- not providing a search option
But I think my #1 complaint with web designs is a printer-friendly page that isn’t printer friendly. I.e., it clips off the copy on the right margin.
Here’s a thought for web designers: If you go to the trouble of making a printer-friendly page, you might at least have the courtesy of making it printer friendly.
