Describe the solution you'd like
Add to GUI and CLI option like this: --proxy 1.1.1.1:1234

Or with file like this:
1.1.1.1:1234
2.2.2.2:4321

And use available proxy from file.

And... I think need to do random proxy for second variant or anything else.

You know how to set proxy in java on Linux? (In command line, dynamic set)
I need proxy now, but I can't find solution.

I edit the source code of proxy, but it showed "connected time out".
Please update the project, thanks!

If you know to do it, can you make a PR? I don't have the time anymore for this project.
Maybe one day, I will have the time to update it
