@joachim-8 : Thank you for your response and my bad for (the promising) Dekko, I had forgotten and I thought about Evolution on desktop (that I use), all these services in a same soft/GUI. So yeah, no problem with email.
As I know the "sync-evolution" solution (I had your article on fav, thank you again for that ;)) is a "command line" solution : make no mistake, I know my terminal and I have no fear in doing little settings. But here my point is that Ubuntu Touch deserve a simple GUI to manage CalDAV/CardDAV connections, centralize and simplify it to the maximum.
I know a lot of people who don't even try GNU/Linux on desktop because "you have to configure a lot of things like the old DOS" and I can't imagine bring them to try a mobile OS with the same arguments. Maybe UT is a bit more challenging than others in a first time but on the basic functions, it should be intuitive to configure. After numerous testings, the whole OS is excellent and yes it's a detail ... but people stop on details ;)
