Add an optional Tab Out behavior that moves a single cursor past configured trailing characters when pressing Tab. Expose the feature in Global Document Settings, keep it disabled by default, persist its configuration, and preserve existing selection and multi-cursor indentation behavior (SpartanJ/ecode#951).
Add an unlocked take-screenshot command and expose it under Settings -> Window with a default Print Screen binding.
Allow configuring the screenshot destination, filename pattern, and output format. Save screenshots under the ecode configuration directory by default, notify users after capture, and provide an action to open the result in the integrated image viewer.
Addresses a request in SpartanJ/ecode#950.
Allow UIFontPickerDialog sections to be hidden and make ecode's UI, editor, and terminal font dialogs select both the font and its size.
Keep external fonts selectable across asynchronous font enumeration, including when they share a family name with a system font, and label them as external. Also normalize UILinearLayout weights across visible children so hidden picker columns release their space correctly.
Update font picker previews, size units, menu labels, translations, and lifetime handling.
Addresses SpartanJ/ecode#944.
