Cyclic structure layering

[XMDS]

The loop keyword is currently used, which looks vague in the editor. When a loop contains multiple loop structures:

if
.......
then
  .........
  while true
     repeat
     ..........
     until .........
        repeat
         ..........
        until ..........
  end

else
     if
     .........
    then
    ........
end

When writing a script with a long code and a complex loop structure, it is very uncomfortable whether it is writing or previewing the code. Perhaps each structure should be made clearer, such as the line box in most editors:

Or there are other ways to make the structure clearer.
