Hi, first thanks for your plugin, it's a core part of my creative process, looove it. I'm working on 360 Fulldome pieces sometimes and I would love to have an equirectangular shape sorting option, if that's even possible (and not sure what the results would be). I've used normal sorting on equirectangular footage then transformed it into fulldome fisheye before, it's working fine but you can see some "stitches" (because the effect is linear and the equirectangular plane is bended afterwards). The other option I tried is your radial zoom sorting on a fisheye footage, working fine, but the effect seems slightly different.
Since you have the dipole and metaphase options I'm naively guessing that bringing an equirectangular shape could be done, but I might be wrong ;)!
Let me know what you think, and keep up the great work!
Best regards,
