There is not much more I can say about this question but the background info is that I require user input while they use my plugin. I have see this done in the Roblox Animation Plugin where you can click animation editor which then shows a gui for user input. The GUI is not shown in the tree so it cannot be deleted by the user which is what I am looking for and also this can be done either while in studio or playing solo.

I could create a GUI then place it into the tree but this will mean that the player can "see/edit/delete" which are things that could effect the plugin so this is not an option for me to use.

The solution that I am looking for is a way of showing a GUI (like a prompt window) to the user while not allowing then to access/edit the GUI so that the plugin can collect the user input.

If you need any more info add a comment.

Thanks in advanced for any help.
