I've tried to figure it this for a couple of days now, but don't seem to get to a good start.
I have 2 things I would like to be able to do in the site content section:

1. Have either additional "sort by date" in the right-click context menu, or have subpages sorted differently (either by date or alphabet) depending on the parent page(for example alphabetical sorting like it is now for regular pages and sorting by date for news etc.).

2. I would also like if one could indicate in the tree for example the page author/owner.
For example like this: "Article Page - Author".

Are these things doable by any reasonable amount of work, and if so where should I start looking?
(couldn't even find where the current context-menu(edit, view, sort subpages) items come from.)
