Hi Timo,
When I use the date picker and click the year, it shows the future years by default.
Can you show the past years instead? Since this is a journal app, I think more people are interested in creating or reviewing past entries. I don't think people will make a lot of future dated entries especially 20+ years in the future. You can display a few future years just in case.
This is my suggestion. It would avoid needing to swipe just to access older years.
