Issue: 2 Questions on how to do.

1. You would have to change the wiki setting under Site Config > Filename of the Wiki PHP File

2. To only show the contents of Astronomy under its Table of Contents section, make sure that the page Astronomy is a book page-type and not an Area or a Category. If it's an Area, you have to rethink your structural hierarchy. A book has to be the child of an Area in order to get permissions from somewhere. You might just have to create 'Astronomy Book' as a new book under 'Astronomy', or you might want to rename the 'Astronomy' area to reduce redundant names.

Also as a feature request, can you add a sideblock for image attachments?

If the URLs didn't change when you changed that setting, change Wiki URL Format back to the first option, then change it back to your desired choice.

And I think I understand what you mean now. Under the area's list of pages, you want it to only show items that are book-type, and not other types, but you still want to allow non-book-types to be created there? There is not currently a way to apply a default filter (or any filters) on those types of content lists. You will have to request such a feature by opening a feature-request, or you should move the chapter-pages to a sub-area that is hidden from users by setting a display order of 0.

ok that worked, thanks.

Yeah i don;t want the pages to be visible like that, it leaves it messy. In fact when creating a page, there should be a option to have it visible or not visible in the index, cause some pages i might want visible as it would be standalone.
