When i had started I also had some trouble managing the HUD (Yes I know i'm and Idiot)
However if you're having the same issues here's some insight that I hope helps.
============================================================
When you start out your HUD should look like this.
============================================================
As obvious as is, you can use the tools bars and note pad like a normal window. Simply hold the top and move it where you see fit.
============================================================
Hitting this button here can enlarge your canvas space to what ever you need.
============================================================
============================================================
Now this isn't really anything worth mentioning, but it's a neat little tip I found useful in many situations. If you move the windows below the screen you'll have more space to see the game.
============================================================
Sometimes it's nice not to have 2 giant windows hogging up 37% of the screen at all times.
