Better "My Collections"

Currently you have just a list of unsorted "My Collections", where articles, images, posts and models are stored. It just a total mess.

1. Separate the collection listing for each type (Images, posts etc).

2. Sort alphanumerically

3. Allow sub-directories or personal tagging with search options

4. Allow search options using tags that you provide

5. When trying to save a new item in a new created collection, when collection is created it should save it there, rather than having to press save again.
