* Enabling/disabling bug fixes (for now, you can enable them all at once, then turn off all the ones you don't like)
* Added some of the customization options (just numbers that can be increased/decreased, sliders don't really seem to be appropriate there)
Yeah... this is probably not good behaviour, because it may be unexpected to suddenly have the menu close because you hit a random key.
For now, I changed it so that only keys with the Ctrl modifier (e.g., Ctrl+R) get through.
And I added backspace as an alternative way to leave the menu, and the spacebar as an alternative way to select a menu item.
OK, I made it brighter, and added a white bar to the left of the rectangle to make it extra visible.
