The current integration with Linear is not ideal. It simply creates a comment that contains a link back to the post. Linear has support for issue links for quite a while, so I am wondering why those weren't chosen in the first place. Intercom does this, and it allows us to filter by issues linking to a certain site, which makes building custom views a LOT easier.
Linear also just launched a new customer requests feature that allows us to collect feedback from different sources within Linear (like Intercom, Canny, Email, ...). Since Canny is just one source this is something we'd like to use - but can't.
