Quickstyle 1.0.9 has a small bug fix
The ⌘+ and ⌘– keys may not have been doing the right thing for you, depending on another setting. When the setting “Take over ⌘+/⌘– keys for whole page zoom” is enabled, these hotkeys are supposed to increase or decrease the zoom factor for the whole page—just like the built-in Safari Zoom In/Zoom Out commands—regardless of the preferred resizing method. But because of a logic error, if your resizing method was set to “Prefer zooming”, the ⌘+/⌘– hotkeys were setting the font size for the whole page instead.
I’ve corrected the logic, so now these hotkeys will always change the zoom factor, not the font size, for the whole page. But if you want them to change the font size, you can press ⌥⌘+/⌥⌘– to accomplish that.
