wondering too - also please integrate all of bootstrap this time.
I'm tired of fiddeling around just because i want to use something RT template doesn't have included from bootstrap.
Core joomla 3.3 uses Bootstrap 2.3 as the officially supported library. This creates some challanges and issues for developers who want to use Bootstrap 3 for their projects. Currently Joomla extension developers are hard pressed to support both 2.3 & 3 in their extensions. If you really want Bootstrap 3 now you could use the following method to convert Bootstrap 2.3 to Bootstrap 3.0 using No Number's ReReplacer plugin. The ReReplacer plugin is likely your best option, but may also result in site problems since much of your site is likely developed to only use Bootstrap 2.3.
But you missunderstood my intention - my problems are exclusevly for the Front-End of RT Templates that are built with Gantry.
My Apps run in the site with the Gantry Template and my intention is to give my users best possible look & intutive usability.
Bootstrap 3 brings more options to the table regarding usability and open source plugins.
But I already explained my Problems in the Dev section and I'm sure Gantry 5 will bring us a bunch of integration options.
