GORDON142 Jdarkroom does everything this app does the same way textedit does everything MS word does.
jDarkroom has nowhere near the options Writeroom has, and it doesn't integrate well with the Mac OS at all. For example, unlike Writeroom, jdarkroom does not support standard Mac OS text services (spelling/grammar, all OS Services menu items, dictionary lookup, etc), and for that matter, it is simply a plain text editor while Writeroom is a rich text editor with good support for formatting. It can even open and save to other formats. Again, if Jdarkroom works for you, great, but asserting that it "does everything writeroom does" really just demonstrates that you haven't used either application.
