@[deleted]: We focussed on building a new theme base which allows us to integrate bootstrap in content. Additionally a lot of missed features are implemented, too. Here you can see the new frontend themes live:http://demo.osticket.direktmarketingtool.de/1.9.13.001/http://demo.osticket.direktmarketingtool.de/1.9.13.002/Read the information pages and you can get an impression, what we have done.With this themes we implemented in the backend the ability to write bootstrap code in the editor, use some "forbidden" tags and something more. Last week we have finalized the implementation of an override system, which allows us to do "virtual" changes on the core files without affecting the original code. At the moment we are starting to rebuild the complete backend, not only to make the backend responsive, the aim is to improve the user interface and user experience.
