Show a message in each most valuable pages in Matomo to explain why it's important #13716

To remind users why particular features/pages in Matomo are important, it would be valuable to show users a notification message, which reminds them of:

• What is this
• Why is it important
• Where to learn more
• Could even show a video showcasing/explaining the feature

For example it is needed to explain to users why "Goals" are so important. So when people click on a Goals page, the first time, they would see a notification message explaining this, with links and video.

It will be also valuable for people browsing our Matomo demo so they can learn more about value of the product while browsing the demo.

Notes:

• A user could close the notification so it does not display again.
• Ideally we would do this for all major pages, but we can add them slowly.
• maybe this could be merged with/rethink of the (?) Help feature within each report
