Extensis Suitcase Fusion is a font management utility that gives you control over all of the fonts on your system. Suitcase Fusion allows you to locate and activate fonts only when you need them and automatically activate fonts for documents through auto activation plug-ins for popular design applications, as well as on a system wide level.

Key Features include:

• New Adobe InCopy plug-in: now you can be sure that the InDesign documents that you share will be displayed with the same fonts everywhere.
• Add colour to Previews: you can now set the font and background colours used in the Previews pane.
• Favourite fonts: mark fonts as favourites and easily find them when you need them. Use them to search fonts and create smart sets.
• Focus on the view you prefer: hide either the Previews or the Fonts so you can see more of what you need to see.
• Work with Fonts inside CS: take your font browsing straight into Adobe Creative Suite 5+ using the Extensis font panels.
• Flag Your Faves: now you can highlight your favourite fonts and quickly save them for use in a future project.
