Describe the bug
If you have some nested markdown widgets and editor components, the dropdown's overflow will not be visible beyond the upper scope markdown widget. In some instances, it also hides below the field header below (screenshot 2)

To Reproduce

1. make sure to have a few editor components
2. create some nested markdown fields
3. try to access the last item on the dropdown

Do you have any plans to also process JSON files? That would be really handy!

e.g. I have JSON files in the /data folder that contain absolute paths to images ("/assets/etc.jpg") that, similarly, need to be converted to relative paths.

The About Page of the app should have the following information,

• GitHub Link to this project
• Twitter link to reach out to, https://twitter.com/tapasadhikary
• Blog link to reach out to, http://blog.greenroots.info/
• Website link to reach out to, https://tapasadhikary.com/

Also, the information should be organized correctly.
