I'm not a native english speaker, and I'm not sure I understood your sentence well, it looks ambiguous to me. Did you say that installing Catorise Plus will erase the categories and sorting we've already done with the old Catorise, or at the contrary that all our settings will be kept and reused in Catorise Plus? Before I install Catorise Plus, I would like to be sure.

By the way, do we need to uninstall Catorise and Catorise GUI before or after installing Catorise Plus?

Thanks for your answer and your great work, and sorry for my awful english!
