New Project: Twitter Bootstrap
The right-hand pane of the Project Category and Options dialog box looks as follows when you choose Static Web in the left-hand pane and then choose Twitter Bootstrap from the list in the right-hand pane.
The feature is supported only in the Ultimate edition when the HTML Tools plugin is installed and enabled. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins page as described in Enabling and Disabling Plugins.
