User Style
The 'Time Mapper UHD' is designed with many changeable options. You don't have to change things, but if you do, there are a great many things you can change, such as the colors and fonts and styles of many of the 50+ map layers. All the settings for the map layers are remembered separately for each Base Map: there are currently 25 of those. But what if a number of people are using the 'Time Mapper UHD' on the same computer, and they each prefer to have things set just the way that they personally like it? That's where the 'User Style' tab-page comes in. You can have all of those settings for all of those layers and all of those maps assigned to a specific 'User Style', then swap between 'User Styles' to get all of your settings back. There are 9 'User Styles': A-I. They have default names: 'Style A', 'Style B', 'Style C', etc., but you can change those if you want to, with any name of up to 16 characters, using only characters A-Z, a-z, 0-9, and Space.
When you visit the 'User Style' tab-page, you will see which 'User Style' is currently selected. Any changes that you make using the 'Layers Menu' will all be changed to the selected 'User Style'. If you select another one, then when you close the 'Settings Menu', all of its values will be used, and any subsequent changes made in the 'Layers Menu' will be saved to that new 'User Style'.
Initially, all the 'User Styles' have the same values: these are the default values. You can always reset the values in a 'User Style' back to the default values by using the buttons available: either resetting the selected 'User Style' for all Base Maps, or just for the Current Map. There are two types of default values: choose '4K' if you are using a monitor with 4K resolution ie 3840 x 2160 or similar; or choose 'HD' if you are using a monitor with HD resolution ie 1920 x 1200 or similar. The difference between the two is that some of the label settings are chosen to be more appropriate for that resolution: larger for 4K, smaller for HD, so the screen isn't swamped with large labels.
