Thanks for bringing this up as a separate request. In another topic, I alluded to this kind of feature:
We also intend to provide a preference to enable/disable: the menu bar icon reflecting whether the current item has any links (or the number of links). E.g., suppose you’re reading a PDF that has 3 links, the menu bar icon would reflect that somehow (possibly showing the # of links).
That is also a concern of mine.So I should not have said “we also intend to provide” but “intend to investigate”. We haven’t delved into it deeply yet. The feature would need a lot of thought and testing. And the user would need to be able to turn it off (as @quorm mentioned), and possibly configure it further (e.g., excluding certain apps from such monitoring).
And we will listen to the community to make sure we develop the best way of meeting the requirements.
