Although I extensively use the web viewer, there are certain sites that I’m always going to want to open in the default browser (for instance, docs.google.com, youtube.com, facebook.com) because of the required functionality, authentication, etc. While I can do this manually with the context menu, I think it would be very handy if the web viewer settings included a section where the user could define URL patterns that should always open in the default browser - that provides faster access, no special mouse click, and a consistent experience once the user sets it up.
This could also largely solve https://forum.obsidian.md/t/some-mouse-shortcut-for-open-link-in-default-browser-bypass-web-viewer/96429 as well.
