Is there a way to specify that a presentation should only be used if a certain condition is met? The use case I have in mind is adding the Magritte presentation to object, but only showing if the object has a Magritte description. It is a PITA to have to copy/paste the presentation method into every Magritte-described object...

use a when: clause.
For example, look at:
FileReference>> gtInspectorPngIn: composite <gtInspectorPresentationOrder: 0> composite morph title: 'Picture'; display: [ self binaryReadStreamDo: [ :stream | PNGReadWriter formFromStream: stream ] ]; *when: [ self mimeTypes notNil and: [ self mimeTypes first matches: ZnMimeType imagePng ] ]*
