It would be nice to be able to, while in 2d, select items that are 'underneath' other objects.
Now you have to go into View Manager and make the top item unselectable. If they are both the same type of element, you have to go to 3d just to select it, then go back to 2d, then open the menu, select previous, then make the change.
All other CAD programs I've used have simple ways to complete this operation. For instance, TC automatically displays a drop-down list of any objects that are in the cursor's "wheelhouse", and lets you decide which one you want to select.
