"Books" with Knowledge base

Hello!
I am lecturer in secondary school in Finland.
I publish a lot of teaching manuals and task in WordPress pages.
I have been testing knowledge base and it is almost what I need.
My pages could be found from here.
Some feature what should be in knowledge plugin.

1. article order should be possible to change from admin page. Example alphabetical order
2. article amount in gategory page should be possible to change. Example only one page or amount of articles in page
3. style of link in gategory page should be possible to change
4. sorting articles in other order. Example if I publish manuals and later I thing that those articles are in wrong order, I could arrange only one article to different place
5. Automatic article number in title of article. Example part 1, part 2, part 3.

In future it would be nice if you could but price in some articles and some are free. Maybe this is totally other plugin. 😀
Sorry about my bad English.
 
Best Regards!
