I am developing Joomla sites for some clients and testing out a number of different templates. So far all the 3rd party templates I've tried seem to be meant for a specific purpose and layout, and customizing them creates more problems. I need something that's more flexible which I can use for any Joomla site I create for different clients. I'm hoping that T3 on its own (the full package) could be the answer to my prayers, perhaps customizing one of the built-in templates.

My concern is that if I have other templates already installed (testing) that are also based on T3 framework, will that cause problems for either the other templates or for anything I develop directly using T3? I don't want to delete the other templates just yet until I know I have a better alternative, so I'm cautious about just going ahead and trying it, in case it messes up what's already there.

Does anyone know the answer to this? Many thanks in advance for help with this. :-)
