Thanks for your comment and suggestions. Maybe some background information. I am a technician and in my free time I do some programming stuff (hobby). Some time ago, I decided to built a GUI interface for frequently used comment line tools which was more convenient for my colleagues. They prefer to use a graphical interface on Windows. Now I decided to put everything together and make them accessible for others. I totally agree to port the tools to other platforms, as I said Linux is in progress. For Mac OS it is kind of difficult because OSx is not common here and I don't have a OSx device. I might decide one day to invest time and effort, I will see. Since all this is done in my free time, implementing and debugging is a bit slow :-)
I am not sure what you mean by command line option. My tools are based on command line programs and basically just connect them with a user friendly interface.
