There are times when I have things to do and I need to upload recently taken photos to send to somebody or some other purpose.
Time is critical. Waiting for an automatic process to get around to noticing changes and getting around to uploading is not an option.
At present, sending myself an email is faster even though there are a lot more steps involved, including waiting for multiple mail servers and the internet to transmit the file out and then back again.
I want a button to push that forces all new photos uploaded immediately as fast as possible from my phone to my computer - which are connected to each other, so it should happen in seconds at most.
While not as critical to me at this point, a second button to force file sync, immediately, in foreground, be the primary data transfer process is also not a bad thing to have.
