'Start Landing' always launches the first 'Configuration'

The active configuration is expected to perform something after clicking that button. See the link:

Small but very simmilar issue. If I open a scene from 'Project' window, the first 'Configuration' tab becomes visible

I agree that this is confusing.
Here is what we should do:

• We should merge both UI's
• As for the adding, we should add an option to use "as defined by build settings" or add an option to override landing for the editor.
