Mini Preview 1.2 Has Been Released
The latest version of Mini Preview contains bug fixes and enhancements.
Mini Preview now displays the latest autosave draft. Clicking [Refresh] triggers autosave and when this is complete, the mini preview window is updated. The same goes for [Preview in New Tab], you will see the latest autosave draft.
If you want a quicker refresh, you can easily skip the autosave by holding CMD (Mac) or CTRL (Windows) when you click [Refresh] or [Preview in New Tab].
For a complete list of the fixes and enhancements see the Change Log.
