Charles Millerwrites about
user interfaces and the trend to put up klunky dialog boxes to confirm
"dangerous" actions. The dialogs rarely stop anyone from making a
mistake. Folks will just click on them automatically without thinking about
them. I know I do.
Charles writes: "Make your actions undo-able. Make your deletions
un-deletable." Then the user always has the ability to undo any
accidents that may have slipped past his fingers.
This is a great idea. I know that when I started using Emacs as my main
editor, it changed the way I editted text. Emacs has an unlimited undo
feature, where you can undo the file all the way back to the beginning of
the edit session. Suddenly I was no longer afraid to try out new features
in the editor. Sure, it might screw up the file, but savlation was only a
few keystrokes away.
Let’s start a campaign to rid the world of those annoying
confirmation queries!
