Proposed improvements.

First and foremost, I love this project, made in native languages, it's super fast and lightweight
, for real, thanks you so much for creating this project. Keep on it!!!

I'm a hardcore proxy software user for web applications security analysis. I just wanted to propose some features or user interfaces features which me (and many people I think) would love to have:

• When repeating a request, it would be great to see the response on the same popup, this way I could make modifications to the same request without pressing "Edit and repeat..." every time. For real, this could be super super useful. Also, a shortcut for "Edit and resend" would be great.
• Scope filter: It would also be super useful to have a filter where I can add scoped domains, so only the domains in the scope are shown (it can be one or more).
• I don't know if it's possible now but, It would be great to have an option on preferences to auto-enable HTTPS Response.
• It would be great to have a "tool" or feature to decode response and request data. Many times, web applications uses Base64 and URL encode on the requests parameters or on the response, it's incredibly useful to have a "right-click > decode as..." and a "right click > encode as..." menu.

Sadly I'm not a good C++/Swift programmer, if it were, I would implement those features myself. Again, I love this project, please, do not give up!

Edit: It would also be great to make this project open source, I think many people could be interested on improve this project.
