Hello there,
Just wanted to post a couple more screenshots for the upcoming mob heads/icons update, since I've had quite some progress since the last post.
You can now see how the settings UI would look like and based on that guess what sort of customization would be possible. All vanilla mobs are now supported, as well as texture packs. It turned out to be a lot more work than I had anticipated but it should be worth it. A lot of mobs even have mob variant support, for example horses and cats (+ more). I'm planning to include even more mobs variants in another update. Most bipedal + "ageable" modded mobs should be automatically somewhat supported as well. For modded mobs with more unique models I'll have to add support manually, which is something I'm probably going to do for popular mods in the future. And the disabled heads/icons buttons in some entity categories are there for a reason too, as I'm planning to add support for all categories in a future update :) I really hope you enjoy the update when it's released! I'm going back to work now. Hoping to get the early access (shared folder) out tomorrow.
Thank you very much for your support!
