Bookmark stations

[matteo-pacini]

Provide users with a mechanism to quickly save and access their favorite radio stations within RadioGoGo. This will allow for quicker navigation and enhance the user experience by personalizing their station list.

Feature Details:

1. Bookmarking Keystroke: Introduce a dedicated keystroke (e.g., B) for bookmarking. When a user highlights a radio station and presses the bookmarking keystroke, that station should be added to their list of bookmarked stations.

2. Bookmark List Access: Users should have an easily accessible section or list displaying all their bookmarked stations, possibly accessible via another keystroke or at the start/top of the station list.

3. Visual Indicator: Within the main station list, there should be a clear visual indicator (like an asterisk, a star, or another symbol) next to each bookmarked station's name.

4. Removing Bookmarks: Users should have the ability to easily remove stations from their bookmarks, either via another keystroke or by toggling the bookmarking keystroke on the highlighted bookmarked station.

5. Persistence: Bookmarked stations should persist across application restarts. Consider storing them in a local configuration or cache file.
