Hello,
here are news from BBSrceenShooter.
A new beta version is out with new feature based on user request.

New in Version 1.51e:
- in the password window the corresponding PIN of the device is displayed
- you can take screenshots from up to 4 devices connected to USB simultaneously
- the device PIN can be included in the file name (it will be included anyway when taking simultaneous shots)
- the rememberPassword feature works for all 4 devices as well (still no button for that, you have to set rememberPassword=1 in the .ini file)
- when doing simultaneous screenshots a combined picture is stored in the clipboard while the files are still saved separate.

Have fun while testing.
Attached are some screenshots. (only 3 devices at once, that's all I have )
