Hey! Sourcegrapher who works on the browser extension and other integrations here.
The road to complete integration in a product is a bit longer as it takes collaboration if the product isn't open source. This is what we'd like in every product we integrate with.
However, I just did quite a bit of refactoring to make it easier and more straight forward to add support for new code hosts to the browser extension.
If you want to add support, we'd gladly accept a PR!
Thanks for the feedback! I'm glad it's helping you out in your day to day.
We're currently working on bringing the extension to Safari. This makes the extension more aware of browser differences which will allow us to keep everything polished in all of the browsers we support.
Keep your eye out for updates and as @sqs said, we'd love to hear any feedback you come across @srcgraph!
