Bug 473321

Summary:
Add a button to the KDE Itinerary application that allows users to search for currently available transport connections, similar to the functionality provided by e.g. long-pressing the selected time in the Transportr application.

Background:
If I want to search for a connection at the current time, the time and date of the last search destination is currently displayed in the search field. It would be helpful to add a feature that allows users to quickly search for connections that are available at the current time. This would provide a more seamless experience, especially for users who need to make last-minute changes to their plans or want to take advantage of immediate transport options.

Proposed feature:

1. Implement a "Now" button within the KDE Itinerary search interface. This button should be clearly visible and easily accessible, preferably in the main search bar or results page.
2. When the user clicks the button, the application should automatically use the current time as the departure/arrival time for the search. The users should have the option to override the current time if they wish.
3. The search results should display the available connections departing or arriving within a short time frame (e.g. the next hour) and highlight the earliest options. Users can then select a connection and proceed to get more information if needed.

Benefits:

- Provides a quick and easy way for users to find immediate transport connections, reducing the need to manually adjust departure times.
- Improves user experience by providing a more dynamic and flexible search option.
- Allows users to take advantage of last minute transport opportunities or make spontaneous changes to their plans.

By implementing this feature, KDE Itinerary can further establish itself as a versatile and user-friendly transport planning tool.
