As a newcomer to the idea of TeX and completely at sea with the various components and varieties of the Algebra and Tex filters, I cannot understand why there are two. Does the TeX filter do the job or not? Obviously not, otherwise, why have an Algebra filter? If it does not do the job required, then why include it? Is Moodle trying to be all things to all people? This is not Ford or GM, why should Moodle need to be? If I am sensing the drift of v2.0 there is a number of things that are essentially adapted from other, existing apps, TinyMCE NWiki, et al, so why not the TeX filter?
