@Isaac-Flath do you think this would be a good fit for the gallery?

[Isaac-Flath]

Yes, I think it's a great fit for the Gallery. It would be nice to have this as an app under the "Start Simple" application section

I will add it to the list to add there and hopefully get to it soon in the next week :) Or if someone has time to make a PR, this would be the steps needed:

• [ ] Take screenshot and GIF of app
• [ ] Create Info page following the rough convention from other start simple app
• [ ] Create metadata.ini file
• [ ] Optional - Make minimal examples of pieces for widgets section if it makes sense (not completely sure it does here, but maybe a file upload example?)

OK I'll close it here so we can move to the gallery.
