Proxy support

[N1N74]

Hello!
The app is partially successful using bridges or snowflake proxies in censorship circumvention and mostly fails or works unreliably. However, one reliably working tool for me has been powertunnel which I am able to run in proxy mode. Powertunnel is sufficient for circumvention for me but it is not capable of hiding ip. Would be useful to be able to use bitmask routing traffic through powertunnel. Powertunnel itself is an anti-DPI tool, so anything equivalent to that would be an alternative to supporting proxy. For context I am only using default powertunnel settings.
