  • trunk/ICeCoffEE/ICeCoffEE/ICeCoffEE.m

    r66 r74  
    66- Carbon contextual menu plugin which presents Services (yah!)
    77  for both files and text
    8 - Carbon version
    9 - app exclusion list - make a pref pane (see AquaShade config)
    108- if it's not a URL, try using TextExtras' open list
    119- John Hayes' suggestions
    12 - ICeCoffEE 2 functionality (bookmark helper app for cmd-option-click)
    13 - adjust URL blinking
    14 
    15 Carbon support ideas:
    16     TEClick - TextEdit
    17     TXNClick - MLTE
    18     ? ATSUI
    19     WASTE has its own support
     10- _LSCopyApplicationURLsForItemURL - list apps
     11- Menu on command-option-click: add bookmark, open with other helper, pass to configurable service, ...?
     12- TXNClick - MLTE has its own support in Jaguar and later, but it's lousy
    2013
    2114Done:
    2215
     16- TEClick - TextEdit
    2317- flash on success (like BBEdit)
    2418- display dialog on failure (decode OSStatus)
     19- adjust URL blinking
     20- app exclusion list - make a pref pane (see AquaShade config)
