I'll will start by apologizing if this isn't the appropriate area to post this question.
I've been using WordPress for a very short period of time, really just using other people's themes and modifying them (i.e. using my own header image, etc.)
I'd like to attempt one from scratch.
My question is: what tools do you use to create themes? Do you use some of the CSS/PHP/HTML editors out there? Do you code using something like Programmer's Notepad? I have been playing with WeBuilder 2006 from Blumental's - it supports CSS, HTML, PHP, etc. and provides the dandy little reminders of all the properties that I can't remember at this point.
What graphics packages do you use for creating backgrounds, headers, etc.? Do you find some programs offer features & capabilities that others don't that are important for WordPress development?
Are there any other design tools out there that you just can't live without?
Thanks in advance for sharing your experiences.
