Web-assembly powered WYSIWYG LaTeX Editor, supporting nearly all LaTeX package
Personally I hate Tex/LaTeX and I think it should be replacted by something else long time ago. First of all syntax is horrible, if you don't work with it on daily basis try to figure out what macro you wrote one year ago is doing. Each time you have to jump to manual and learn almost everythig from very beginning. Next thing is lack of utf-8 and TrueType fonts supports (I know there is XeTeX and LuaTeX) but today such features such be in very core of text system no in some software branch. Extensibility is next thing and here again it is very poor unless you use something modern like LuaTeX or you are an expert in TeX macros. Packages dependency hell is next thing side by side with stupid compilation process with meaningless error messages. Am I the only one who think this way?
