[Ring] File sharing

[Óvári]

Hello,

This relates to the file transfer feature in Ring advertised at:
https://ring.cx/en/news#file-sharing-now-available-in-ring

When transferring files:

1. Can multiple files be selected in the "Send File" dialog box, eg 
using Ctrl+Click and Shift+Click?

2. Is there a Progress Bar showing the percentage/size transferred?

3. Does Ring show the "Expected time remaining" for file transfers?

4. Can file transfers be Paused and Resumed?

5. When there is a conversation with Multiple participants, how does 
Ring display the progress for each participant?

6. Would it be helpful to list YouTube videos showing how other software 
implements this feature?

Thank you
