The usual procedure is to write the pages in the browser edit window, and press Preview to see the changes.
Doesn't fit, as what I would like to accomplish is e.g. (and especially) doing hard work on the templates and forms (I'm using Semantic Forms) and see the changes on the rendered pages using those templates and forms. Just to clarify: imagine "Test Page" is rendered by using three templates: "Template 1", "Template 2", Template 3". So I want to load "Test Page" in the browser, and "Template;Template_1.txt", "Template;Template_2.txt" and "Template;Template_3.txt" files into my text editor (ps: no inotify here, I'm on a windows platform). Then if I make changes in all those three .txt files, when I press F5 in the browser it should render the page according to my changes.
