Many thanks for these responses and the detailed information. Very helpful, especially the point about Python. I do use the SkinVue scripting utility and if there is no python 3 upgrade for that then I wouldn't want to move to a version that didn't support that. in terms of the other highlighted items, I've dabbled with displacement and might do so more if it has been improved. Can't say it's a wow factor improvement but, yes, it is interesting to me and counts as a mild plus. Ditto cloud improvements. I like playing with the clouds in Vue, so definitely some stuff that appeals to me in that list but whether it is worth the cost (and the risk of losing other things I am likely to use/need more) is still hard to say. I'll keep thinking!
