English: Currently, syntax highlighting colors the text background if the text is within a template or a so-called ParserFunction. When working on templates or editing pages with many nested templates, this can lead to almost all text being highlighted, thus creating confusion instead of clarity.

This suggestion is therefore to not color the background of these texts in general and instead only highlight the innermost function or template in which the cursor is currently located.

In the graphic, the cursor is located at the selected position within the 'if' function, so the entire area of this 'if' function is highlighted with a red background. This makes it easier to see what belongs together both as someone writing code and as someone looking to understand what another user has written.
