4/* To do/think about:
5
6- TXNClick - MLTE has its own support in Jaguar and later, but it's lousy
7
8Done:
9
10- TEClick - TextEdit
11- flash on success (like BBEdit)
12- display dialog on failure (decode OSStatus)
13- adjust URL blinking
14- app exclusion list - make a pref pane (see AquaShade config)
15- _LSCopyApplicationURLsForItemURL - list apps
16- Menu on command-option-click: add bookmark, open with other helper, pass to configurable service, ...?
