As a developer, I like to keep Developer Hub articles open as I work for quick reference. I usually also have the Dev forums open, sometimes even on multiple tabs.
It’s just a minor annoyance, but I very frequently mistake Dev Forum tabs as Dev Hub tabs, and trying to find the right page can take me twice as long as it actually should.
See this example:
Can you tell at a glance which ones are from the Forums, and which are from the Dev Hub?
Even with the titles, you can’t.
Changing the icon would help distinguish documentation from discussion, and would make the lives of many multi-tasking developers a little bit easier.
