@D-livil: another suggestion as the packaging of themes into secondary packages is already done.

Would you mind thinking about packaging colors together? Like all blue variations in one package, all green ones, all yellow ones and so on. Updates of theme packages would decrease in size and the user would have the ability to choose a base color (i.e. the corresponding color package) and then select the favourite flavour like plain or liquid.
Your packages are again getting really huge and today's update just fetched about 40MB! Much of the content I will never use as I don't like the base color.

So far thanks for your fantastic work!
