1. Add a view range button in the layout editor.
In the editing view for your layout, there should be a button to allow you to see the range of all your defensive buildings. This can help view what/where you have covered in your layout and how you want to adjust it.
2. Troops that target defense should be able to attack heroes.
In the game, Heroes are considered both troops and defensive units. So like defensive units, they should also be targeted by giants/bloons/etc. I would add in that they should be able to attack clan castle as well, but my main focus would be towards the heroes.
