If I click on the balloon with the i in it I get the text on the right side of the screenshot. When I hover my mouse over the link the curor changes shape as is expected when it is a hyperlink. However clicking the link leads me no-where.
Thanks for reporting. Will be fixed!
To further add to this. The new version of the Tess4J node, nightly build, has a hyperlink in its Node Description. The same story here as above.
