I've decided I need ideas :p
And somewhere to update the (probably inexistent, due to the project's inactivity) public of the addon. Here I'll be posting updates made to the addon, planned changes and sneak peeks of things. I'll also have the latest update's changes on the OP (Original Post, aka this post).

For now, I'm planning the following:

• Remove garbage files left over from testing I was doing
  
• Rework the addon from the ground up. Including models, scripting and whatever else there is, cause this thing's pretty outdated.
  
• Add TEXTURESSSS!!! Something I've wanted to do for some time but just freaking couldn't!

Started modeling the room itself.[i.imgur.com] Just threw some shapes around and liked it, so I kept it :3
