(Suggestion) Paint Textures on models/Models showing where to paint

[LucarioRanger]

I don't know about everyone, but I have had an impossibly difficult time finding good ways to texture on my custom models in Tabla, heck, even trying other programs. I don't know where each part of the model is on the little texture box in the corner, and as such have had such a more difficult time trying to texture my models.

My Proposition:
Either have a basic painting tool in Tabula to let us 'paint' directly on the models, and save it as a PNG file so you could open it up in another art program to fine tune it
or
Have more clear indication on what is what on a model (Such as showing where a leg may be on the texture map)

Again, I Don't know if this is just me being bad at not knowing how to texture models, or if others have issues, (I'm very new to this) but in my SS below, you can see where the "body" is supposed to be on the map, but I can't figure out how to know where the body is to texture in another program. Or if I just paint each part individually on one PNG file then move it by offsetting each part of the model
