What tiny thing in Lion makes you smile or has caught you off guard?

Solution 1:

Using the FaceTime camera to add signatures to PDFs in Preview.

Click the annotations button in the toolbar and use the drop down menu next to the signature icon to grab your signature from a piece of paper you have written it on. Then just click and drag in the document to place it. Haven't really needed it yet, but it's implemented so nicely that I did it just for fun.

Solution 2:

Finder - make a new folder with a selection of files

Given the number of times I'd have to do the Cmd-Shift-N/highlight/drag dance, this is by far my favorite:

New Folder With Selection

Solution 3:

Accessing accented characters has been made a lot easier.

Just hold down the letter and a list of alternatives will show. Awesome.

Example of OS X Lion accented characters popup menu

By pressing the number and continuing to type, the desired letter replaces the e and alows you to keep your fingers on the keyboard. Double Awesome.

This behavior can be turned off. Turning off this new feature allows the traditional key repeat function to work for all keys as shown in the keyboard system preference window.

Solution 4:

All window edges allow resizing

How about ability to resize windows from all edges of the window?

The reduced clutter of not having a resize nub is nice, but the power comes with these options (which can be combined):

shift - maintains aspect ratio while sizing
option - maintains the center point while sizing
