I have only just got to look at this new software (installed version 3.0) and I think it shows great promise. I installed all the extra theme packs (individually extracting them all into the styles sub-folder) only to realise I may have to do the same thing again when I upgrade to version 3.1. Is there a way of not having to repeat this process? Can I copy the styles folder elsewheere and copy it back once I've uninstalled 3.0 and installed 3.1?

I did not lose any of my templates when upgrating from 3.0 to 3.1 and then back to 3.0. Nothing wrong with 3.1 I only went back to 3.0 because I had to check on something I had edited (at my own risk) on a template and not saved..dumb:/

To be safe then sorry it is a good idea to create a zip file of the templates you
already unpacked.

If you lost the newer templates after installing the new version it's because you uninstalled the old. Just reinstall your template compressed files. all will be well:D
