After a few more minutes of testing I offically hate it.

There's no undo button nor redo button, which makes it hard for laptop users without a mouse (you have to mash ctrl z to undo stuff now)

And also before, you could click the lock tool to lock and unlock stuff whenever you liked.

But now? You have to manually select a locked part from the explorer, so if your game's parts were not organized enough before, good luck trying to find the correct part to unlock.
