4 | /* To do/think about: |
---|
5 | |
---|
6 | - Carbon contextual menu plugin which presents Services (yah!) |
---|
7 | for both files and text |
---|
8 | - if it's not a URL, try using TextExtras' open list |
---|
9 | - TXNClick - MLTE has its own support in Jaguar and later, but it's lousy |
---|
10 | |
---|
11 | Done: |
---|
12 | |
---|
13 | - TEClick - TextEdit |
---|
14 | - flash on success (like BBEdit) |
---|
15 | - display dialog on failure (decode OSStatus) |
---|
16 | - adjust URL blinking |
---|
17 | - app exclusion list - make a pref pane (see AquaShade config) |
---|
18 | - _LSCopyApplicationURLsForItemURL - list apps |
---|
19 | - Menu on command-option-click: add bookmark, open with other helper, pass to configurable service, ...? |
