If I wanted to hard code margins, padding and borders into every picture I wouldn't be using WordPress.
Wow. What unbelievable arrogance. Do you understand that the idea of an upgrade is to IMPROVE a product, not to cripple it? It's not about providing makework for programmers either!
I use the margin/border feature on every site I manage (dozens) multiple (dozens) times a day and you just increased my workload EXPONENTIALLY.
Just because the [moderated] at wordpress.com don't use it doesn't mean that applies to professionals.
And I want the ability to redirect the image source from the image editing window back too.
I am SO angry.
And no I don't want to add more plugins to sites (to DOZENS of sites) to replace a feature that YOU took out. Especially since the more plugins, the slower the site.
