I'll bet this has been suggested already (I couldn't see anything though)... if so then please delete and point me to where it has been asked already.
When cloning an object (copy / paste clone), it should really be like an exact duplicate of that object, effects and behaviours included. This enables easier level editing and testing. Especially for physics stuff. This is something I noticed from the first time I toyed with Construct. Now that I'm testing physics stuff it's just more noticable.
Would be nice to see this fixed for a future update
