[feature-req] Delete elements from array-like structures from the explorer with point and click

[nmingotti]

I find sometimes this feature to be very handy while modifying running software. I mean, i would like to remove an object i see in the explore with something like: point and right-click + select "nuke this object". It should be not much difficult to do but requires familiarity with the GUI elements which at the moment i don't have. I leave it here to remind myself or some other intermediate users to implement it.
