This plugin works well; is very easy to set up and get started with almost right away.
I think to improve what already exists, I would like to see:
Higher customization in terms of visual quality of life, such as the ability to move/resize the text box and the option to not filter the background gameplay.
Personally, I would not use this right now because the event obscures the gameplay too much but I really do like what you have made here - it has a lot of potential and I will keep an eye on it for the future.
Thank you for your good work :)
