Anything I can do to improve usability of 'Solution Explorer' in VS2008?

Question

In solutions that contain a few different projects, I find myself constantly shuffling around in solution explorer looking for a particular file, when the tree gets expanded a little, there are often 4 'pages' of files to scroll through.

Does anyone have any tips for making solution explorer a bit more usable?

Perhaps Some 'collapse all folders' shortcut? or Some way of colour coding different projects?

I'm guessing theres not much that can be done, but thought I'd ask. I've got tons of horizontal screen space utilizing this in some way would be good.

Thanks

UPDATE Regarding the right click context menus on solution and project nodes, here's what I have:

Answer 1

Get Visual Assist X from Whole Tomato. it adds a number of hotkeys and nice features for opening files and finding stuff.

Or upgrade to VS2010 if that's an option. Visual Assist X is much cheaper :)

Answer 2

Edit The ReSharper add-in adds a "Collapse All" menu item to the Solution Explorer's right click menu (it's way down at the bottom of the menu, and easy to miss).

Also, I really like ReSharper's Find Usages functionality, and do most of my solution level navigation that way.

Answer 3

键盘也可以使用，只需键入文件名的第一个字母即可。
