MCPE Model Maker for Minecraft

So I really like this, but why is there no place that you can build your own custom thing custom things are the coolest things plus when you’re making skins you can’t make it wider if you’re making your own skin, could you please add those things so we can do that

This app is very good I really recommend but it’s really hard trying to access like blockbench on this and unity too so maybe people can use it very easily but it’s pretty hard to access blockbench and unity or something like unity but it’s needs like a button somewhere to access blockbench and that stuff and i can’t make my model into a resource pack or that stuff for Minecraft so it needs two things a button for blockbench and that stuff and it needs to be able to make the models into recourse pack for minecraft.

It’s a good app but I can’t access the model, iPhone users can’t access the path given after the model is saved so can you help me
