I take snapshots frequently. It's a pain in the butt to manually name every one. Please come up with an automatic naming scheme similar to SL's. I suggest you name them using "Sansar - YYYY-MM-DD - NNN.png". And please let us choose JPEG, too. For example, the third picture taken today would be named "Sansar - 2018-04-11 - 003.jpg".
You guys really need this feature to be able to make snapshots in VR mode practical, anyway. But it would be nice to have a keyboard shortcut devoted to this. May I suggest CTRL-~ (tilde), in keeping with SL's familiar shortcut?
