“This piece of ugly looking unformatted code” – it’s my standard formatting. It’s ugly because it uses 2 spaces indentation? Maybe it is, but write 10k of code (as one file) and you’ll notice, it’s sometimes hard to fit all you need on screen. So, call it ugly, but it is not unformatted.
This indent code is good but how would you do an indent from a dropdown list, indenting item 2-10 and 12- 15.
