If you've gotten used to working with the project panel in list format, there are a number of enhancements which could lure you finally to switch over to an icon view. For a start, now you can scrub through a clip preview simply by waving the pointer left and right inside its icon. If you click on the icon, a playback head marker lets you do this more precisely. Hit the appropriate keyboard shortcuts, and you can even add or edit in and out points. There are icons to show whether a clip has an audio or a video track, and hovering over these tells you whether the clip has been used in a sequence. Click on the information pop-up, and you're taken straight to that location.
The timeline has seen some changes too. The separate scroll and zoom bars have been combined, with the latter removed from its position above the media tracks. This takes a little getting used to, if you're familiar with the previous way of doing things, but it does make navigating through an edit with the mouse that little bit quicker. The feedback when your mouse pointer moves over the ends of clips is now much clearer than before, with bright red arrows appearing so you know precisely whether clicking will drag the left or right clip's end point. Double-click on an effect, and it will be applied to the clip, or clips, that are currently selected on the timeline. You can now adjust effect parameters whilst a clip continues to play from the timeline, too.
There are some welcome improvements in the effects department as well. Adjustment layers have made their way across from Photoshop and After Effects, although they function in a slightly different fashion. They are added as empty clips, to which can be applied any filters desired. Place them on the timeline, and all clips beneath will be treated - handy if you want to uniformly filter a complex picture-in-picture without the complication of a nested sequence.
Another immigrant from After Effects is the Warp Stabilizer effect. This is a very powerful image stabilisation tool, with lots of configuration options, and even tools for reducing the effects of rolling shutter caused by the sequential scanning of CMOS sensors, or the "jellos" as they are affectionately called. There's also a separate rolling shutter corrector, if you just want this facility on its own. The three-way colour corrector has been redesigned, too, with a Master button to gang all colour wheels together, individual wheel eyedroppers, and a general reordering to make oft-used functions easier to find.
