Magpie 1.4: keep the keys you already know
Every Mac user has ⇧⌘4 in their fingers. Learning a new set of capture shortcuts to use a better capture tool is a small tax, but you pay it every single time, and for the first week you mostly just take macOS screenshots by accident.
Magpie 1.4 adds shortcut styles in Settings ▸ Shortcuts. Keep Magpie's own ⌥⇧ keys, or pick macOS keys and Magpie takes over ⇧⌘3, ⇧⌘4 and ⇧⌘5, plus ⇧⌘6 for window capture, switching off macOS's own screenshot shortcuts so the keys you already know open Magpie instead.
The part I cared about getting right is giving them back. Switching styles, or using Reset to Defaults, hands the keys straight back to macOS, and only the ones Magpie actually switched off are ever restored. An app that quietly rewrites your system settings and can't undo it is not a trade worth making for a screenshot tool.
First launch asks which style you want, right after the permissions step, so the decision happens once at the point where you're already making decisions. Capture History has its own shortcut now too, ⌥⇧H by default and configurable like the rest, and Reset to Defaults restores every shortcut rather than just the capture ones.
Magpie is $9.99 one time for 3 Macs, with a 14-day full trial and screenshots free forever after that. Grab it from the Magpie page or with Homebrew: brew install --cask skulkworks/tap/magpie. Full details are in the changelog.
