Ux to define link copy and placement:
Currently looks like this for reference:

@pwalm, we're also looking to add a link out to Extension Workshop somewhere in the top part of the page -- can we get your thoughts on where?
Mid term plan: it'd be great to get a banner that goes to Extension Workshop to replace the "Welcome Back" banner. Would you have bandwidth to take that on in the next 2 - 3 weeks? If not, we can work around it.
(We'll also add a link in the "Documentation" section below.)
I'm going to narrow scope on this for the moment and request that we add Extension Workshop to the header between My Add-ons and Documentation.

Link text: Extension Workshop
Link target: https://extensionworkshop.com
Next steps:
We are hoping to land this in the next 1 - 2 weeks. @championshuttler, @suhailsinghbains, or @xu3u4, would any of you have any interest in picking this issue up?
@caitmuenster Sure, Let me try to take a look , in the meantime if someone else is able to raise PR, feel free to do that :)
Revised link for tracking: https://extensionworkshop.com/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=devhub-menu-link
Same utm_source for prod, dev and stage?
Asking @jvillalobos to comment ^. :)
Yes, it's used for keeping track of things in Google Analytics, so it shouldn't matter if it's dev, or others.
This was already verified here https://github.com/mozilla/addons-server/issues/10909
with FF65(Win10).
