Provide ability to add Folders, for example used for data and images

[brettforbes]

It'd be great if there was the ability to create folders, particularly for data or images.

IT starts looking ugly once the number of data files creep ups (e.g. switch between options with radio button needs 6 files)

Great point! Directories are work-in-progress. You can put slashes in the file names to create directories. However, the files only load correctly if there is an index.html present.

See this example:

We definitely have more work to do around directories. I'd break it up like this:

• [ ] Support directories in the V3 Runtime (with index.js and no index.html)
• [ ] Improve UX around directories ("new directory" button, drag & drop files between directories, create new file in directory)

These issues are mapped out in more detail here: https://github.com/vizhub-core/vzcode/issues?q=is%3Aissue+is%3Aopen+directory
