Yes, I often need to cross reference specific commits or branches in several places, this would be ultra helpful (at least to be able to copy the link).
Currently I can only find "(open)" which opens in github next to the commit sha1 on the commit panel of the log view from the working tree window (A) ; but I'd like to have this especially
- (B) when right clicking a commit in the journal panel of the working tree view

- (C) in the history tab of the standard window, in the right click menu when clicking a commit AND next to the commit SHA1 of the  commit view (similar to (A)

Examples below :
