Keeping snapshot windows on top

By default, snapshot windows are at the same level as any other normal windows. Therefore, if you select the main windows, the snapshot windows may be hidden behind it. Skim allows you to keep all your snapshot windows on top of the main window, so they are always visible.

To keep snapshot windows on top, choose Skim > Preferences, click General, and select "Keep snapshot windows on top".

In full screen mode, snapshot windows are always on top.
