I have updated Shoehorn for both Moodle 2.8 and 2.9 (Moodle version 2015042400.00 release 2.9beta+ (Build: 20150424)). You can get the code from:
M2.9: https://moodle.org/plugins/pluginversion.php?id=8427 - alpha version for test servers.
The changes are as follows:
1. Fix source map URL for development version after upgrading to 'grunt-contrib-less' version '~1.0.0'. 2. Tidy up logo code and information in language file. 3. Tidy up experimental RTL serving. 4. Tidy up and fix syntax highlighting - work in progress. 5. Adjust carousel control icons responsively. 6. Messages popup on the left to avoid anti-gravity icon. 7. Tidy up compact navbar. 8. Remove dependancy on parent 'bootstrap' theme. 9. Update to Bootstrap 3.3.4. 10. Update to Font Awesome 4.3.0.
Critically after much deliberation I have detached the theme from the parent 'Bootstrap' Moodle theme. Such that the theme works out of the box without needing to install 'Bootstrap'.
