[Feature Request]: ChatGPT support #122

Feature Description

This was originally from Discussion, now moved to issue tracker since there is following descriptions below that would potentially add more support to extension:
"Originally a Perplexity AI extension, this repository has now been restructured into a suite of enhancements for multiple platforms and services."

Hello, I have been using Complexity extension very useful, including on both PC and Mobile version.

Currently, there is no better open-source alternative to this extension for ChatGPT (Actually there is Superpower ChatGPT already, but this extension enforces users email to subscribe to their newsletter without their consent so it is considered as a malicious), so it would be great if this extension could expand support to ChatGPT, which is popular AI Chat worldwide.

Thank you so much for making this extension.

Use Case

Similar experience for ChatGPT with various features from userscripts with theming for ChatGPT. Examples can be found here.

Alternatives Considered

Make as a separate extension if it doesn't seem to fit with Complexity.
