Purpose
Now, you need to manually copy line by line if you want to copy multiple scripts. It is so bothersome that I would like you to add a feature where we can copy multiple lines at the same time.
But How?
Look at the Fig 1.
Fig. 1: The image of the new feature
By dragging a screen without anything, a translucent blue square shows up and changes the color of the code blocks which are included by it in terms of y-axis. Then release the left click and press right click, and there will be a toolbox that has some actions: Copy, Paste, Cut, Delete, Run-on-client, and so on. Those actions are applied to all the lines.
Conclusion
It will not only reduce the time to copy the lines but also the stress of the game devs! Thus I believe it is a very nice feature to add.
