Thank you for the clarification on the matter.
I have no experience with Python, hence my fear about installing it. If I
understand correctly, after it's installed it can automatically download and
install proprietary modules if they are required by another application,
correct?
If that was not the case I would happily install it. But as it is now, I will
have to stick with OnionShare 1.3 :( for now it's not a problem, but if a
serious security bug is ever disclosed I don't know what to do. There are not
many alternatives to this kind of specific tool...
