This is at the forum level to sort topics. This can be done from admin too that in what ordering you want the topics.
Looking for this option within a topic so posts are shown by the last reply. So the functionality you are showing is what we need, but within a topic. Will be great if can set parameter in forum settings (in admin) for the sort order for posts within a topic, similar to setting ordering of topics within a forum.

Currently all the posts in a discussion topic is shown in chronological order (latest post at the end). Should have an option to show posts in reverse chronological order too, where the latest post comes at the top, below the title. This is important since some discussions, the latest information matter more and then this would be logical and intuitive. For example, if the topic is discussion of some live event development, the latest update is most relevant rather than the first reply after topic was started. This feature was present in version 3.X. Please consider adding this in 4.X since extremely important for us.
Please contribute if anyone else also finds this relevant so the IPS team can consider taking it as a task in an upcoming update. If someone has a quick fix to achieve this, that will be helpful too for now. Thanks!

Not a filter. But just show all replies in reverse order. So for example if this is current the ordering of the posts -
Title matter --- posted on July 1 at 10am
Reply1 - July 2 at 10am
Reply2 - July 2 at 11am
Reply3 - July 4 at 10am
Reply4 - July 8 at 9am
Show it in this manner (in reverse)
Title matter --- posted on July 1 at 10am   --- stays as title
Reply4 - July 8 at 9am
Reply3 - July 4 at 10am
Reply2 - July 2 at 11am
Reply1 - July 2 at 10am
So the reply that is shown at the top is the most recent reply since as information was updated the latest reply probably has the most relevant information.
