Start where you left off. (timestamps)

[alannssantos]

This is already my favorite client, but searching for where I left off is
complicated when you use it on multiple devices or don't have time to
watch it completely at once.

If there was a way to get the API timestamp and start with it and at each
time interval it sends a push to the API updating the server timestamp.

I believe that with this, the part that marks as watched would no longer
be necessary.

Thanks!
