PS. I like to be consistent in the naming, but what are the guidelines?
Guideline1: classname = filename. Because classnames are in uppercase, files are also named in this way. src/insets/*, src/mathed/* and src/graphics/* follow this guideline well so these are what I have renamed so far. Guideline2: clean or merge helper files. If they can not be merged, some special format may be used although I tend to continue to use upper case (for visual consistency, although inconsistency is desired by many :-). So, let us decide between a. FrontendHelper b. frontendHelper c. Frontend_helper d. frontend_helper This format will also be applied to _fwd and _pimpl and _funcs. Cheers, Bo
