To whomever implemented this thing of beauty:

YOU GUYS.
You should put this in a release note so you can take credit for it and get a bonus or promotion or however people advance inside of Atlassian.
So what you're looking at is the perfect answer to my "meh" response to the original introduction of Folders.
- They didn't really have permanent links - if you did manage to find the Copy Link option for a folder, going to that link redirected you to the first page in the folder.
- You didn't get a list of child pages/folders, so it was actually worse than creating a "parent page" with a pagetree macro.
This is GREAT new functionality for folders:
- Folders have their own unique URL and "landing page"
- They have graphical headers (removable and customizable)
- They list all TOP LEVEL pages and folders (also databases, whiteboards) in the folder
- You can also list the objects in a Grid!

(Hrm, the Grid option does not stick, but maybe it's just as well as I would think they should instead show a thumbnail of the page header instead of that weird whiteboard-looking thing.)
But at any rate, great improvement! Whoever implemented it should get credit!
But um, also: Why was this not in any of the 3 different release notes?
Also not tracked by any of the third-party Atlassian release notes trackers:
C'mon, you create something great that is NOT AI-related and doesn't change existing how we work, and you don't let us know about it ahead of time?
I guess surprises can be nice, but still! Get your props!
