A new tool to import/export your mail and settings in Evolution

A few days ago I was looking for a guide to export my mail and settings (my accounts, address book, calendar, filters, etc.) to my laptop and I found a few guides. I wondered why, as far as I know, there is no way to export my data in Evolution (my favourite email client)…

then I asked myself whether I should depend on those guides every time I need to move to another OS or computer. Ok, a script that automates the whole operation already exists but I wanted something more flexible and I found it somewhat absurd that I had to read a guide or use a script to export my data. I just wanted a GUI which could save me the time to find the script (my hard disk is a mess) or to find and read a guide (is it laziness or just lack of time?).
