So I've got this really cool idea of mine:

You know the Multi-Select option in Fine Tuner?

What if, we could make this great feature one step better with this cool (and arguable) idea?

How about this, you could select multiple parts at once!

No like, seriously. Life would be way better instead of having to click at parts multiple times.

Here's a great example of what this idea could be in the game.

And I will demonstrate it, with another game.

(pls don't mind this horrible mess of a level)
This game is called Geometry Dash. And there's an option in this game's level editor that lets you select multiple parts through a swipe (see gif above). Also the same thing on GD's PC counterpart, but with the mouse.
Not only is this option helpful for the game's level creators who want to delete multiple parts at once, but to also copy and paste multiple parts. Copy-paste already exists in SP, so why not spice it up a bit?

Now, imagine this feature but in SP.

I WILL BE IN FREAKING BLISS IF IT DID!

Let me know your opinions on this suggestion, and what else you want to add to it!
