In segment editor, the *Effects* part does not show entire options. How can i add more options to Effects part?

Operating system: 64 bit windows 10 Pro
Slicer version: 4.11.20210226
Expected behavior: I expect the Effects part on segment editor to include the entire options.
Actual behavior: the Effects part only includes a few option tools on the stable version that I downloaded.

It depends on what extra effects you need but you can get some additional effects by installing the “SegmentEditorExtraEffects” module from the Extensions Manager. Other effect add ons are also found in the Extensions Manager.
