About the Red Wedding sets, yeah well you're right, but why not rename them all to Red Wedding (1,2, and 3)? That way, they should show up one after another, instead of Set #5249 breaking the flow. (Btw, it would be nice to be able to see the set boundaries... 😁 )
Sets are not organized by name, just in order of creation, so right now the only way to change it would be almost doing the whole episode from zero (and it's not easy lol). When I have the option to change the order of the sets I can do that more easily.
But as you say, now it's done, I realize it somehow breaks the flow in this particular case and just for 2 pictures (I thought maybe there would be more in the future for that meeting, with GoT you never know). So I'll change it in the future probably 😉
About the boundaries it could be nice, though I'm not sure how that could be done in some easy way for the gallery show.
