Say I have two windows of Google Chrome, with each having multiple tabs - Is there a way to merge the two windows? (except for manually dragging the tabs one at a time from one window to the other?)

The Windows To Tabs extension for Chrome will do the trick.

You simply hit a button in Chrome and all tabs from any open windows are merged into one window.

In fact, there are loads of extensions out there, like JoinTabs which gives you more control over what windows are merged into what other windows.

See my answer which notes that extensions are no longer needed to do this same function (since Chrome version 24) – Seph Feb 20 '15 at 13:02
The problem with using extensions for tiny items like this, is that each extension uses another 10-20MB of RAM. Chrome is so memory hogging when it comes to extensions. :( – NickG Apr 17 '15 at 8:39

This functionality now exists in Chrome and has since version 24 or earlier. - So no need for extensions (any more)

Left-click the first tab in the window you want to merge, then hold the shift key and left-click the right most tab. All of the selected tabs for the current window can now be dragged and dropped as as group on another Chrome window.

Awesome! It works great. – B Seven May 29 '15 at 2:02

One of my favorite extensions (certainly the one I use the most) is Session Buddy. It's so incredibly useful and merging windows is just one of it's many many features.
