Does the queue group cloze and image occlusion cards at the end?

How does the queue actually work?

From my own subjective experience it appears to group cloze cards and image occlusions towards the end (rather than mixing them with basic and concept-descriptor type cards).

Any plans to change this behaviour or add the ability to randomise it? SuperMemo and Anki both seem to randomise type order by default.

Yeah children rem are definitely given one after another and image occlusions towards the end; but once i have done a document for the first time, it will henceforth recommend stuff according to its algorithm; images coming at end is pretty weird tho
