This feature could apply to many widgets:

• Weather
• Chemical Elements
• World Countries
• Cryptocurrencies
• GitHub Stats
• Twitter Stats
• YouTube Stats

I've been already playing around with this idea, but I haven't found a good place to put such a link so far.

How about the text next to the GitHub icon? In the code, I think it's called the "headline". I actually kept clicked there, initially.
