The Nielsen Norman Group (NN/g), a user experience firm founded by usability gurus Jakob Nielsen and Don Norman, has appraised iOS 7, and the verdict isn’t great. “Early experience with applications redesigned for iOS 7 is fairly negative: several have worse usability than their iOS 6 versions.” In particular, NN/g cites action labels that are indistinguishable from content, the confusing date picker, confusing swipe actions (for example, activating Notification Center when you wanted Spotlight), and the redesign of many icons, of which NN/g said, “Apple has demolished millions of hours of user learning by changing the icons.” However, NN/g said that iOS 7’s design isn’t fatally flawed, and praised how controls are hidden in Safari, global font size controls, and the streamlined Settings app.follow link
Mysteriously Moving Margins in Word
In Microsoft Word 2008 (and older versions), if you put your cursor in a paragraph and then move a tab or indent marker in the ruler, the change applies to just that paragraph. If your markers are closely spaced, you may have trouble grabbing the right one, and inadvertently work with tabs when you want to work with indents, or vice-versa. The solution is to hover your mouse over the marker until a yellow tooltip confirms which element you're about to drag.
I recently came to appreciate the importance of waiting for those tooltips: a document mysteriously reset its margins several times while I was under deadline pressure, causing a variety of problems. After several hours of puzzlement, I had my "doh!" moment: I had been dragging a margin marker when I thought I was dragging an indent marker.
When it comes to moving markers in the Word ruler, the moral of the story is always to hover, read, and only then drag.
