I've been using SEEdit for a while now, and it's become my favorite sitebuilder. It does not crash, unlike many/all of the others I've tried, and it's quite agile. It has autocomplete, spellcheck, tidyHTML, while at the same time organizing all of your files for you into their respective folders. Sven is the most mindful author I've encountered, offering solutions and recommendations, support, and new versions CONSTANTLY. I believe it's every week that a new version of the beta arrives, which is easily obtained as SEEdit checks automatically for any updates, which you can restrict to only full releases or betas. I use it daily to instruct in my classes, and find it very navigable and customizable. It works hand-in-hand with your CSS editor, or you can use it instead. It has taught me quite a bit, also, as I instruct. If you submit a problem, you can count on getting a reply within 10 minutes, and a fix in either the current week's release or the following. This is how applications were meant to be supported, long before the huge corporations took over and blotted out the sun from smaller developers. I will NEVER be without it! I don't usually comment on alot of software, but I believe that every Mac user should buy a copy of this software, even if they're just learning.
