i’m gonna disagree a little bit with Nate and say that the HIG guidance allows for an opt-in tray icon, and then also agree with Nate when he says it should be handled within spectacle.
spectacle should offer an opt-in tray icon that users can access without the need for a shortcut key bind.
and perhaps at the same time streamline the print screen shortcut to afford a menu of all the capture options without having to remember half a dozen variants on the shortcut.
that said, i would not want to eliminate the half dozen shortcuts for those who are already used to them or have customized them to their needs.
this definitely falls into the feature request category, and i’m moving this to brainstorm.
edit: looks like partial implementation along these lines is already in work.
