Develop a new button labeled "Aim" positioned adjacent to the existing "Change" button. The "Aim" button should be styled with a yellow background. Upon clicking the "Aim" button, a dropdown or menu should appear, presenting a selection of aiming reticle options, including the default reticle. The design of the alternative reticles should closely resemble the aiming reticles depicted in the provided images, utilizing only programming elements and avoiding any AI-generated content. Ensure the implementation is consistent with the existing codebase and user interface.
