Feature Request: Allow synchronizing smallest files first.

[RokeJulianLockhart]

Is your feature request related to a problem? Please describe.

I've a very slow internet connection, and frequently need to move from place to place. This means that I need to be able to sync what I can in the timeframe I am provided.

Describe the solution you'd like

In my case, I solely care about being able to synchronize the smallest files first.

Describe alternatives you've considered

Allow the user to order how the files from the server should be synchronized more generally, including this. This is the best course of action because it means the logic is less custom for each option added subsequently.
