Disabling the v3 Chat Bar GUI

[ChibiChibiLuc]

Is there any way to disable the chat bar that comes up when you hit tab in v3?

I wanted to rescript a bar more like the v2 one, but there're a few problems:

First of all, is there any way to disable the bar from popping up? Like a ChatGUI.destroy()? Enablefeatures doesn't work.

Second, is there any way to detect when the tab key is hit? I've tried keydown2(9,true) in both a keypressed and a timeout, but it didn't register.

Third, is there a way to force select the custom GUI bar where you input the text with a command?
