My Star Wars shelf has undergone a couple changes through the years. I did vanilla posing for so long to cut back on space, but after getting rid of some figures and having a little extra room, I experimented a bit with posing, and I don't know if I'd ever go back now. It just breathes so much life into the display. I totally get the desire to keep things chronological; that was me for a while too, until I just had too much to deal with. In order to utilize the space better and not have one movie/show bleed onto another shelf, I had to go in order of how large each section's offerings are; now it's spread over a couple shelves, with those shelf organizer things to help utilize the space better- OT/ST on one, Prequels/Clone Wars/Solo/Andor on one, Rebels/Rogue One/Fallen Order/Survivor/Kenobi/EU on one, and Bad Batch/Mando/Book/Ahsoka on another. Skeleton Crew and Acolyte (and Jabba) have little sections kinda off to the side currently. I thought it would bug me, not being chronological, but it hasn't; if anything, it's freed me up a bit to be a bit more clever. There's no saying I can't change it again if I wanted to.
I ended up having to use an entirely different shelf for the army builders- clones, droids, and otherwise (not Mandalorians, but I'll probably soon have to implement that change as well). Means that some of the commanders/named clones aren't in their trilogy spots, but that's okay; I wouldn't have room for the main characters otherwise. I don't have nearly as many as I used to, and I sold off a lot of the extras I had, but they're the ones that I'm mostly keeping in vanilla poses for now to cut down on space usage, mostly because the clones and stormtroopers
can stand in vanilla poses and still be screen accurate.
Far be it from me to tell you how to do your display, I'm just saying, as a recovering chronological truther, there is life on the other side.
