A Microsoft file hosting and synchronization service.
It's a crappy engineering decision from a user experience point of view. I am a Heavy user of Onedrive and here are some pointers to make this **** better:
1.) allow us to sort based on "created date", not just "modified date".
2.) make the default sort on created date and descending. This way, I always see the most recent files first, in particular for photos this makes a lot of sense.
3.) Speaking of photos, I have absolutely no way to sort within Albums. why the heck is that???
4.) And when I add photos to albums, the list of albums provided to me is in no sensible order. At the very least, the list of albums shown should be in alphabetical order as I try to find the album I want to add the photo to. Just a terrible user experience.
