Command interface improvement

I enjoy making commands in games, but I have found that editing massive of instructions in both Java and Bedrock versions is a very difficult task. I just ask that the editing page of the command block be improved to a metaphor in the picture(java edition, and how do I upload pictures?)? Just like this, a expand button has been added to the first image, which looks like the second image when expanded. The command area is larger, and the mouse can be directly dragged to select. At the same time, an up and down scrollbar has been added, which will definitely make editing commands more efficient! I really hope you can adopt this suggestion!
