Best Practices for using QML and QtQuick
summary
Keep QML files small, aim for keep files under 300 lines and split components when they exceed ~500; set an ID on every item and name the root item "root" for clear references; expose only interface properties at the top and hide internals with a QtObject id trick; avoid findChildren/objectName; prefer QQmlObjectListModel for models and batch-insert items; use fast reload (filesystem watcher or Ctrl+R), printf-style console.log snippets, and Image.sourceSize for thumbnail performance.
