Im not sure this is what you were looking for, but i find a great way to have an easily available link to parts, blocks and symbols is to create a shortcut tool on your windows toolbar that reference to a library folder.
This is how you do it:
First create a library folder somewhere on your disk where you create and organize all kinds of subfolders.
For instance; Gears, bolts, hubs, etc...
Put all your parts, blocks and symbols in these subfolders.
Now right click your windows toolbar and go to "toolbars"
(im not sure thats the right name as mine is in another language. But its the first one from the top of the list)
- then click "new toolbar" - Browse to the library folder you just created - and click ok.
Now that a shortcut to your library folder (containing parts, block, and symbols) should be available at all times in the lower right corner of your windows toolbar.
Whenever you need a block you can click this shortcut that will expand the whole list of library folders and parts.You can now just "drag" the block you want into your drawing from this exopanded menu.

I would show you an image of how its done but i cant figure out how to post images in this reply.
