copy/paste request

[Darkseid-vrr]

Hello, i am using your editor a lot of time and i really appreciate your work which i think is almost finished.
however i create this issue because i think there is a feature cruelly lacking : the copy/paste.

i am aware that you are focusing on actual functionnalities from the game itself (as developpers).
but i want to give you my feedback from the point of view of a user.

the copy paste is necessary when we have the ambition to make an actual full level (and not just experimenting some testing).

to be more precise, here is a suggestion of how it could be working :
we could have the possibility to draw a rectangle and add all the actors in that rectangle into the current selection (it must not deselect a previous set of actors, it perform a "union set" operation).
for example we could have : "clic (outside of any actor) + slide + release" to draw the rectangle.

if we do "clic + release" without sliding (and outside of any actor), it will deselect everything just like current behavior.

and then right clic and "paste" to paste a copy of all selected actors to a new location.

thanks for reading my blabbering.
