I am using sitecore 8.2 (rev. 161221) and I am trying to learn Sitecore Speak UI.
I follow the steps describe here but the custom tab is not visible.
What I have created in core database
Let me know what I missed so that the new tab is visible.
You need to add at least one Chunk with some element, e.g. Large Button, to your Strip. Otherwise it's invisible.
