Within the search option there is a possibility to narrow down the search results by filtering. This may be helpful, but I think there should also be filtering options at a higher level to narrow down the visible parts of your journal, while keeping the full functionality of Diarium.
For instance if I want to see where I have been during a long holiday, I can look in the timeline or create a tag for that specific holiday, but on the map I will still see all places where I have ever been.
If it was possible to use global filters, I could create separate diaries for every holiday on the fly.
