Ok - perhaps requiring only multipart feature inputs is too extreme. How about: 1. We drop the field group option, for the same reasons initially described (there's better algorithms to do this) 2. Add a new boolean option for which creates as single hull for all features in the layer Would that work? Alternatively we could have two algorithms: 1. Convex hull - operates per feature on just the geometry for each feature 2. Layer convex hull - generates a convex hull covering a whole input layer (By the way - I'm not trying to go full "unix philosophy" here (since that's a flawed premise anyway!). It's more about dropping/fixing badly designed options when better alternatives exist).
