I would love to see a random character filename placeholder in a future version of Greenshot. I've seen this feature in "Shutter" for Linux.
Example:
${RRR} or ${R}${R}${R} prints eg. z3Y.
This would be very useful to me when I don't want people I share images with to be able to find my other screenshot pictures (I'm uploading the images through WinSCP to my domain).
Hey, nice idea, thanks for suggesting this
In the meantime, a combination a combination of time and the incrementing number is probably the best bet - one would need to be lucky to guess a filename (at least if guessing manually)
My implementation of this was just merged, and it’s in pre-release 1.3.116.
