TL;DR
passwords never should never be saved as plain text. The Proxy-Password should be encrypted.What ?
In the current version one is able to configure a proxy with password.Said password is input in a field in the menu as plain text.
The same password is then saved to the config-file in the config subfolder.
Unfortunately it is saves as plain text.
Please hide the password in the inputfield (5 stars or something) and encrypt the saved password!
