MCreator is an amazing program for creating your own mods without programming knowledge, But it's definetely NOT perfect. This is a couple suggestions that i have that i hope everyone that sees this will agree with.
1. Custom armor textures (The model, Not the item.)
This is just something thats much needed, But it would be solved just fine if Pylo would provide texture templates for the armor.
2. Seeds for plants
Again, Much needed. Currently (From what I've seen), Theres no way to have 2 drops from your plant, So it doesn't really make sense unless the produce IS the seed.
3. New potion effects
This isn't necessarily needed, But it would be very nice, But it could also be difficult to implement into MCreator.
4. New enchantments
Pretty much the same reason as potions, It would be nice, But its not necessary.
If you want your ideas to be seen, Comment on this and help Pylo make their app better!
