Upload listening test code on GoListen for large experiments

[PGuiraud]

Hi all,

Just a suggestion for a nice additional feature to the GoListen app.

For large experiment, it would be practical if we could upload the code of the test, in html or other, directly on GoListen.
Having looked at the index.html template on the repo as well as inspecting the source code of a test on the App, it would be fairly straightforward to code and would help avoid potential mistakes from dragging and dropping many audio files.

To keep in mind :)
Thanks!
