For my hobby project about writing microstories (stories with at most 150 words, and based on a photo) I purchased the Mobius theme and plugins.
Now i like to count the views of stories people wrote and published. For that i need to intercept when a user/viewer select a tab. That could be the active tab by default or when someone select a non-active tab to make it active. And then i have to check which story is in the tab 
Is there a function/action/filter available with which i can count the views?
Kind regards,
Hans Stavleu
