Subcategory Reordering for NodeBB
In a nutshell, this plugin allows you to enable automatic reordering by post date for specific categories' subcategories.
For example, if Category
A has three subcategories,
D, and automatic re-ordering was enabled for
A, then any post in
D will change their ordering when seen via
A, by bumping that category to the top.
So when originally the order was
D, a new topic or reply in
D will trigger re-ordering, and the new order
Install via the admin control panel, and restart NodeBB. In the plugin settings, enable automatic re-ordering for whichever categories you like. The ordering itself applies only to the subcategories of the enabled category.
