As part of the "muting" of staff messages @eviltrout will be working on maybe late this week or possibly next week...
This will extend to many other topic state changes: pin, archive, banner, unlist, and so forth. Any message you used to see in yellow will be in this newer, muted style.
I was thinking, along the way we might want to add an option to show category changes and title edits in the same way, inline in the topic.
Kind of like how GitHub does it:
This is, strictly speaking, duplicating the edit history that already exists in the first post of the topic. It would just make category changes and title edits much more visible and public.
Is this useful as a default? Could get a bit noisy if the OP decides to edit their title five times, on the other hand, seeing topics get recategorized makes it clearer when and why "gardening" is going on, etc.
