Use NisA to:store data which you cant (or don't want to) show in a single text file. organize and view your homepage, development project, text files & picture archive... write down your ideas and thoughts and order them in a intuitive fashion.
You can also add png, html, txt, jpg, gif, bmp files to the nisa hierarchy, and you will see that it is rather easy to access the data from the finder/the explorer/the shell.
This is a preview version and free of charge.
Tell me what such an application would need as additional feature to be really useful, and I will include it in a future release.
This application is also available for linux and windows
