Yes, it would be nice being able to select objects that are sort of hidden behind things or to be able to select a group of objects more easily.
One of the following would be nice.
1. Shift-selecting from objects menu as was just mentioned in this thread.
2. Selecting all objects in a container.
3. Selecting all objects in a layer.
The only way I can do it now is have everything I need to select in one layer, and then draw a bow around them. Or if I just want one thing, I need to move stuff out of the way and then line them up again which can be tricky and time consuming.
