Hello,
A very basic idea : the idea to have a custom tooltip on Qlik Sense object with the ability to use already used dimensions and measures (but I want to choose wich one), add other dimensions/measures/expressions and even to add some text.
A huge thing would be to have viz in a tooltip like a well-know competitor but let's call that step 2 😉
Best regards,
Simon
