The Project Info Panel
The Project Info Panel allows you to define project-wide settings for skin, font, and link and selection color. It also contains an area to add notes about the project. Click the icon to the right of the Property Inspector icon to toggle the Project Info panel (keyboard shortcut: CTRL/⌘+,).
These settings will be applied to all wireframes in the project and will be saved with the project (i.e., they persist when the project is closed and reopened or shared with others).
The default font is Balsamiq Sans, just as in previous versions (not Comic Sans as you might think; although you can set it to that, all you Comic Sans lovers out there!).
Note: If you want to use a specific project font we recommend that you set it before you start creating your wireframes. Changing the project font may adversely affect existing wireframes in your project. Each font has different dimensions and proportions so switching fonts may cause controls to overlap or line up unevenly. Also, setting your project font to a variant such as "thin", "light", or "extrabold" may override font style settings on individual controls.
Sketch vs Wireframe Skin
The two skins provided are intended to allow you to work on early ideas using a rough, sketchy look (Sketch Skin), and then later update it to a crisper, more polished look when it is ready for presentation (Wireframe Skin).
The screenshots below show a comparison of a sample design in the default "sketch" and "wireframe" skins, respectively. Click to view larger images.
