CafeTran has been designed to tailor its interface to user's individual preferences. The translator can change the layout of windows, dock or float the tabs with resources. Changing the size of the font and switching to dark themes is possible too.

• Right-click at the resource tab's title to dock, float it or join the tab to another tab.
• Choose another theme (e.g. the dark or image-based ones) in the View > Themes menu.
• Change the colors or font size of particular elements of the interface in the View > Colors/Font menu. To increase or decrease the font size temporarily, use the Zoom buttons in the source editor's toolbar.
• You can switch the editors to the horizontal layout via the View > Segment editors menu.
