if i open a json file "File / Open / EasyEDA..." i can make changes to the json file. if i press save there is no way of saving changes back to the file i opened, It forces you to create an entire project, then download the file out of the project (noting that you have a stupid limit of 10 project downloads a day for no apparent reason) to then have to delete the project that you dident want anyway. there should be some option on this page that just says "Save to File" without having to create entire projects. what is the point in being able to open a file in Edit Mode and then lot let anyone save changes?
