Getting netbeans more eclipse-y

Answer 1

If your project is connected to source control netbeans will show added lines with a green block at the beginning of the line, modified lines with a blue block, and deleted lines with a red arrow. It also marks these in the right margin/gutter. This is based off of compared to last commit, not last save however.

As for the other two I could not find a way to implement them but I may just be missing something
