My only caveats. It's 'branded' —so if you like your HTML output to be clean and free of other developer's URLs and comments you're going to need to get into the code to redact all that. In that sense, it's a kludge: a brute force method of making your CSS work on Joomla. It's also a lot of configuration and it's yet another extension to manage if all you're trying to do is some simple unique page styling; make sure you can't accomplish what you need with template overrides, using the Page Class Suffix, or some other method of granular CSS control-by-page. Finally, I don't know if this will be ported to 1.6 and beyond but due to improvements in the core of Joomla's template engine it seems that a strong designer/developer wouldn't even need something such as this.
But as it stands, for Joomla 1.5., this is a fast way for a HTML/CSS developer to get designs Joomla ready without having to get into a lot of the deeper Joomla customization that can be intimidating.
The branding in the generatortag is removed in newer versions. Kind regards, mediahof
But as others have said, there is virtually no support. For instance styling without hacking the core; perhaps it's possible but it's not obvious or in keeping with MVC. If you have problems be prepared for some work, or be brave.
But I see there is already a 1.6 version and from the looks of thing it has been refactored to make template over-rides easier. So it looks like this will continue to be a 'must have' extension for Joomla for the next generation.
I am very much looking forward to the continued development and future versions of this script. But even as it is this has helped me immeasurably.
If you're a intermediate level developer, I cannot stress how much easier this makes working with a joomla site.
For example, I have a localhost development site, a live test/launch server, and the live site. If I make changes to the live site or the development server, I can make a mirror of the revised site as easily as doing a clean joomla install. Or you can build you're own core joomla install, with all the extensions and changes that work for you, pack it up. And then rather spending the hours re-configuring each joomla install you done as soon as you run the install, and you can get to the business of building your site.
There's a lot of deep control about what and where to pack. So if you think that this has nothing to offer you, check it out. I'll bet you'll be surprised.
One of the best joomla investments I've made. For real.
