This site offers a large library of plug-ins built for InDesign, both for purchase and free download. The tools available from this outlet are top-notch. Each product allows for improved work flow and a reduction on repetitive tasks. The most useful features are the type tools which allow advanced control of kerning and tracking. Cool Kerning allows the user to define kerning values based on a font and adjacent letters, eliminating the need to manually set kerning for reoccurring letter pairs. Other tools are available on the site.
From the site: Cool Kerning lets you do automatic updates of kerning values. You will be able to build kerning tables to control kerning between special character pairs. The tables are collected into packages that have a version number. The packages can be automatically distributed inside the InDesign documents so that . updates are also automatically parsed in your organization. This gives you much greater quality assurance than you are accustomed to in other layout programs. With the Cool Kerning plug-in, you can use fewer designers and still take less time to get to the correct graphical results. It's all handled automatically! Building pages that use headlines often requires manual amendment of the tracking values. Cool Tracking allows you to make tracking tables and automate the process. The use of a graph to specify the values has been seen before. But what really stands out in Cool Tracking is the easy way in which you can store multiple tables inside packages that can be distributed in your organization. This technology allows you to lower your production costs dramatically. And you get quality assurance on a new level that no other layout program can match. It's all handled automatically!
