Dear all, I am thinking about moving from LaTeX to ConTeXt. But there is one thing make this particularly difficult. That is the microtype LaTeX package. More specifically I have the following questions (assuming I will use MKIV and luatex) 1. I understand that ConTeXt can do margin kerning and font expansion, but is there a way to setup a configuration file for each font set. Like the mt-foo.cfg file for font family foo when using microtype in latex. 2. Is there a way to do letterspace in ConTeXt. I understand there is a command called \stretched. But what I want is the feature like the tracking option in microtype package, which can automatically letterspace all small caps. Moreover is there a way to define new sets of fonts for letterspace. For example I defined a new font shape called \capshape, which use case tags of OpenType, and I want to use letterspace this shape with certain amount all the time because I am not satisfied with the space provided by the cpsp tag of OpenType. I am sorry for using and LaTeX terminology. I haven't start learning ConTeXt at all at this stage. I want to first know if it provide all the features I need before I spend my time on learning a new language.
