One thing that I miss is to get information about the size of a folder with all the things in it. I can see the size of the single files, but not the folders size. If I want to know this I have to open the terminal app

The most important thing to me is privacy. Not to be in the hand of Google or apple or windows or anyone else.
It haven't to be mainstream, but it have to respect me.
It is also important to me to use my device as long as I want, secure. And not have to by a new device. (I know this is kind of not realistic because it is in the nature of the things that operating systems need more powered devices when the develloping is going on)

In this context a verry huge thank you to the people of ubports and halium.
