Thank you, thank you, thank you!

I've been looking for something like this for ages. I use QubesOS, and copy + paste between HVM(Windows) and paravirtual domains(Linux) just did not work with Windows 10. I previously used a little webserver on a separate VM on my virtual network where I had to go with a browser to copy and paste stuff in a shared chat window. And files were even worse.

That solution was not as secure as I'd like and necessitates network connectivity between machine where I want to share data. Piknik is still not secure in that sense, but it is much more seamless and can be installed as a drop-in replacement since the environment is so similar to my current solution!
