My new maxim is

“If your feature is not user friendly, it’s just a bug” 

If you want to tell your collegue

 It’s a new feature? But it’s not user friendly?? Hey dude, it’s just a bug!

Usability is a more common word for user friendliness ; this notion is just really important (essential) in any software / web development. I try to apply this notion in the phpMyVisites development. This is one advantage of the open source development style: you have a direct answer from the community which tells you what is good or bad.

Usability rocks!
