But the server doesn’t know when a theme is added. It can be done, of course, by checking the existence of the zip when the list of themes is created. But then, you don’t always have writing permissions. And the theme may be updated without erasing the generated zip. It can probably all be worked out by checking permissions, change times, etc. and choosing the appropriate behaviour.

I’m excited with this and will work on it, but I’ll have to learn a bit of PHP first and then find some time to do it, so don’t hold your breath. I haven’t even started with the cookie expiration time yet.

Thank you for your comments.
