Message # 1
So, when I install custom theme and replace it with default ones from the gallery, almost all modules have "mixed" design from my custom theme and new installed one. To fix this I must uninstall all modules and install them again, then, I have to install again that theme from the gallery.
This is pain in the ass when I want to see multiple themes how they look by installing them on my site.
(I know I couldjust make few websites and install themes there, but I don't like to have dump websites or to use UcoZ's resources more than I have to).
