Various feature requests for navigation and search

[Prime1Code]

Hi Samuel,

So far the project is really great!
Nevertheless, I have a few feature requests that came up while using the web gui in a larger development environment:

1. Saving connection details so they don't have to be entered manually each time.
2. Selection of available hosts in the connection details window
3. Display of the total number of records in the collection in the navigation bar (left side), example: "testCollection (2581)".
4. A separate scrollbar for the databases and collections (left side), so that the whole page does not always scroll when you want to go to the bottom of the navigation.
5. "Expand" and "shrink" on search results should expand and shrink all subelements respectively

I hope that some or even all features will make it into the product.
Keep up the good work!

Thanks a lot
