There is #definition in ClassDescription that you can override. Right now Nautilus actually uses #definitionForNautilus which we need to clean up: https://pharo.fogbugz.com/f/cases/14063/clean-up-definitionForNautilus <https://pharo.fogbugz.com/f/cases/14063/clean-up-definitionForNautilus> This is sadly harder than it should be due to a mess of Monticello using FilePackage to parse smalltalk code… Marcus
