I think we really need a better way to deal with transitions, desktop settings and theme management directly integrated in the CSSU to avoid obsolescence.

Theme Customizer is not maintained any more and using it with latest CSSU results in loosing any changes made by CSSU Features Configuration utility or any manual change.

What I would like to propose is to add more options in the default configuration menu for theme management. Not only the ability to choose a theme but also, choosing the icon pack, fonts or even a predefined transitions file. This way Theme Customizer wouldn't be needed any more.

I would also propose to update packages dependant on Theme Customizer to avoid that dependency (i.e. some icon packs) and theme packs.

Then a transitions tuning utility (such as CSSU Tuner but more fine grained) should be integrated in the setup menu of CSSU. But it's important to separate transitions tuning from any other desktop options enabled by CSSU. Maybe the thp_tweaks section could go even into another file. This way we could have packages for specific transition styles such as a Harmattan Style transitions or the dibble doddle transitions to be downloaded and selected in the configuration menu.

Finally a third item in the setup menu could be a desktop options menu, where the thp_tweaks or other options could be configured.

Hope it makes sense.
