Please make a command in Editor to cyclically move cursor on brackets in code-blocks: ( ), " ", begin-exception-end, case-when-when-...-else-end, if-elsif-else-end if. I mean every highlighted brackets in code. When reached the close-bracket (i.e. "end"), then move to open-bracket in that block (i.e. begin).
Btw, please improve highlighting of case in expressions
