Central Tab Control
The central 'Tab Control' is a collection of 10 Tab-Pages that control all operations of the program. Each Tab-Page is identified by the text on its Tab. You can access a Tab-Page by clicking on the desired tab. See the individual Help Pages for more information about each tab-page: 'Setup', 'Plot', 'Callsign', 'Country', 'Beam', 'Range', 'Route', 'Widgets', 'Solar', and 'Help'.
If you wish to hide the 'Central Tab Control', you can do that by clicking on the 'Hide Tab Pages' button, in the top-right of the program-window. The current map will then be re-sized to use all available space, whilst maintaining the correct aspect-ratio.
Clicking on the 'Hide Tab Pages' button a second time will show extra controls in the bottom-left corner of the map.
Click the 'Hide Tab Pages' button once again, and the program-layout will return to its default settings.
The program has many opportunities to change the color and font of different items, including plotted features, and even the form background color. For details, see the 'Set Map Colors/Fonts' help-page.
