1. HEADLINE: More robust backup tool
As a user who recently switched from Win 10 to Ubuntu Desktop, I tried to setup nightly backups of certain folders to my NAS device with Déjà Dup. After installing missing dependencies and tinkering with the settings for a long time, I finally got it working. Once I did, it wasn't reliable at all. I kept getting various different illegible errors.
IMHO having a robust backup software that just works out of the box would make switching to Ubuntu Desktop more easier and compelling for the average user.
2. HEADLINE: Better GUI to manage VPN connections
Right now there is no way to open the network manager and setup a VPN connection like there is on MacOS. I would like to be able to import my .ovpn file and just click connect.

I must add that I have found solutions to both the above-mentioned issues but they are technical / complex in nature and not something a layperson would be able to setup very easily. Ubuntu Desktop has come a long way but for a desktop OS to be able to go mainstream, things like that just have to work out of the box.
