This is the place to talk smack on frustratingly horrible User Interfaces. Point out all the flaws that tick you off that you have to deal with every single day. Get it out of your system.
(Optionally) If you have a suggestion for a better design, talk about it here. If it’s good enough, let’s team up and bring it to the attention of the developers.
All platforms, all genres of software AND hardware. This is a bitch-fest, not a cat fight.
