In the past, this website had a scrolling up/down arrow on the right side of the page that you could grab it and move up & down to navigate messages within a topic.
This arrow would show the current message number along with the total messages within the topic. It would also show the date of the current message as well as the current message text.
The arrow made it easy to search through past messages to easily see progression of the topic discussion
Just recently the arrow has been replaced with a blue bar in the lower right of the page showing the current message number and total messages.
If you click on the blue bar, the double arrow appears in an empty field and allows you to scroll through the messages on at a time.
This “new feature” in my opinion makes it more difficult to review older topic messages and to get to the last messaged viewed and to the bottom of the message list.
I liked the previous method and actions for the double arrow.
Less complicated & more straight forward to navigate the community web pages.
