[New Feature] Add splitting settings

[Korb]

[x] I have searched on the issue tracker before creating the issue.

(since there is no mention of split tunneling in the README.md, nor in the Issues section, I assume that this function is missing in the application)

I suggest considering the possibility of adding the ability to configure black and white lists of domains and applications. That is, to separate installed applications and internet-addresses into those for which a proxy is used, and those for which a proxy is not used.

This is useful for situations where certain applications or sites do not work correctly when using a proxy, or if there is a need to exclude the use of specific proxies for certain applications or sites.
