I am both web developer and web designer. I need only 4 tools to complete my jobs. They are Notepad++, Adobe Photoshop, FileZilla, and all major browsers. (And my default is Opera!)
I don’t have any problem in coding (except finding how to use some functions). The thing that make me headache is about designing. The most headache problem I always encounter is “I don’t know how width and height the element (or space) is.”
My classic solutions to measure elements are Opera Dragonfly and Photoshop. But, sometimes it’s too slow. So, I am a hot-tempered designer! Opera Extensions save me from being boiled again. lol
My savior is OMeasure extension!
If you’re having a headache with the same problem, install it immediately!
