Thank you :)

Would it also select all the child elements when a parent is selected?

not really... generally in the view2 and most other software, the left click is for a single selection, shift or control + the click is for multiple. In this case, considering we will need to select the parent object only, I felt is better to assign the left click to single selection. if you want to select multiple, simply holding shift and clicking a range of them should work :)
