The stock android calendar shows events happening at overlapping times in stacked order, which allows to still read what they are about, example: <img width="127" height="614" alt="Image" src="https://github.com/user-attachments/assets/e02aac4e-cf8d-4f19-9252-7a2a0c9a2049" /> ETAR instead puts them side-by-side, which makes them unreadable (no visible text): <img width="103" height="664" alt="Image" src="https://github.com/user-attachments/assets/30b6aad6-ef15-463c-99ae-8e5f51ee150b" />
