Panorama / Tab groups are amazingly helpful for this, one of the best FF4+ features. This is another good step towards improving the feature.

I'm not sure how well the Dropzilla concept will work with a large number of bookmarks, or folders within folders, but I look forward to testing whatever they come up with.

I thought the dropzilla concept in the final slide looks pretty similar to what tab groups can already do. I hope they do combine them rather than having the two as separate features, otherwise it'll be splitting up bookmarks in different areas.

The Tab Groups feature is really useful but it's also quite awfully done. I particularly hate the way it resizes and moves around groups when you resize the browser. Ideally, it should use an automated layout, similar to tiling window managers, where you have a fixed master area, and a stacking area for other recently used groups. It'd also be fairly handy if you could nest groups, or have multiple panoramas, for people like me who have too many tabs open to fit on the screen at once.
