The Product Idea boards have gotten an update to better integrate them within our Product team's idea cycle! However this update does have a few unique behaviors, if you have any questions about them check out our FAQ.
Thanks for bringing that to our attention! The information about the Transaction Size for the Output Data tool can be found on the Output Options Help page via a link on the Output Data tool page but we will work to make that information a bit easier to find. Thank you!
My suggestion would be to make section on the page where one can find the pages that give more detail to the subject. A link hidden in a text is not always noticed.
