[UI] Dashboard page could be more useful (Drone 1.0.0)

For now (v1.0.0-rc4) the drone UI looks very polished and is a big step forward compared to 0.8 but I think there are some things which can be improved. Some points I have noticed so far:

  • sometimes it might be helpful to have the option to change the sorting for the repository list in the dashboard or any other method to find “last active” repositories more easily (currently it is hard if you have a large list)
