I am so sick of badly behaved focus behavior! I hate it when websites have onload handlers that do janky things with the focus, moving it to some arbitrary form field, not realizing that many users start interacting before the page is completely loaded. I hate it when desktop applications steal the focus, causing whatever I’ve been typing in some other appication to be lost.
Please, please, can we just all work together for a world where the active window keeps focus until the user decides otherwise? Where websites are smart enough to change focus only if you’re not currently interacting with the page, if they insist on changing focus at all?

I will never hate Adobe enough for the absurd focus-stealing behavior in Photoshop 🙂
The idiot who designed this into Photoshop oughta be hung by his nuts, if he has any that is. How irritating that some bastard designer thought this would be a good idea.
