This is an application i just came across while surfing the web for Typo3 tips and Tricks.
From what i can see, its very impressive and i have to give it some further tries, autocompletion for code, drag and drop for elements, and the possibility to have a database form application hooked within a few mins. Every web developer knows, that most of the time you sit there with your text app and web browser, searching for information or code, that does what you want to do, this application eases up the whole web development process, so that you might have to search the web a little less than usual while doing your development.
