My favourite part of the toolbar is this down arrow, which means you can download a report showing whatever you have in your table right that moment. This is fantastic, because, when you are using the main interface every day (rather than reports which you might use weekly), you get used to a certain way of looking at the data, and here you can export it just like that.

The 'All Campaigns' button drops down to give you 3 choices - All, All Enabled, All But Deleted. The All choice is fantastic, as it allows you to see all those campaigns you might have deleted, so that they aren't really gone forever. I haven't yet found a use for the All But Deleted and All Enabled - and frankly, don't understand what the difference between them is.
Segment
The segment button allows you to segment the results in the table (not in the graph) by timeframe, click type, device and keyword match. Timeframe is useful for comparing adjacent time periods, but is too much information when using the keywords tab. Click type isn't useful for me, because I don't use call clicks. Devices could provide some VERY useful information, telling you how many of your users are mobile, and keyword match is useful for tweaking your campaign.
Filter
Here you can create your own filter to apply to your data, kind of like in Google analytics. You can exclude clicks, costs, conversions, status types and lots of other things, without having to export all the information first.The other buttons are the usual ones - changing columns and graph display.
These improvements to Google Adwords are just making it more and more unnecessary to use other software to manage your Adwords campaigns. I believe that using the normal Google Adwords interface coupled with Adwords Editor, you don't need to use any other software, this should give you all the flexibility you need to manage campaigns of any size.
