Make permissions suggestions work like in-game

[BrainStone]

I think it would be much better if the suggestions only showed the text until the next dot (exlcuding it).
Pressing Tab adds the currently selected suggestion to the textbox but doesn't finish adding the node to the list.
There also should be a button for that (like I'm sure you've seen in plenty of search bars with suggestions that there is a button that just adds the suggestion to the text box but doesn't submit. Typically an arrow to the bottom left)
