Tools of the Trade
As a developer/designer I spend far too much time trying to reconcile the differences between the Firefox and IE rendering engines. I’ve picked up a few habits that make it less painful, but until there is a Firebug for IE, it’s still a long painful process.
The other tool I use on a daily basis as a developer is SQLYog. Couldn’t work with MySQL without this tool.
What applications do you use for development/design?
