There are several aspects of the OverCASE appearance that can be adjusted using the Integrator.

- Look-and-feel can be selected from the "Options/Look-and-feel" Integrator menu. Once selected, the new look-and-feel is applied to all currently running OverCASE applications (including the Integrator itself) and is remembered for future OverCASE sessions.
- UI language can be selected from the "Options/Language" Integrator menu. Once selected, the new look-and-feel is applied to all currently running OverCASE applications (including the Integrator itself) and is remembered for future OverCASE sessions.
- The "quick launch" bar can be toggled by "Options/Quick launch bar" Integrator menu command (or by a corresponding Integrator toolbar button).
