[Pixel Persona, Draw Persona, Export Persona what does it mean?]

I've been finding my way around affinity for about 4 months now, yet I still feel I'm not using to its maximum capability, could you explain in greater depth the differences or different situations in which to use the personas in affinity designer( im more of an example kind of a guy) "monkey see monkey do"

[Personas and Manual]

I love Affinity, Ive used Illustrator at school and it seems pretty slow and complicated to me, yet there are several manuals, tutorials and books to help people like mee understand the software more, i know reading wont make me draw better but it would definetly help me understand more the uses of each personas icon, effect and so on: is there any way I can get anything of this sort? I would also like to understand the different use between the personas

[Pen tool lines keep errasing themselves]

Hello, Im currently tracing an image using the pen tool for a school assigment and as I am doing the traces all of the points or dots I dont know how to call them ( Im just starting with the program), please help! ive noticed that as i finish a line it either turns out to be a square or a circle (do you mind explaining the differences) and I do not understand why as I am trying to make a curved line it becomes longer that what i had initially drawn, (the lines that shoot out of the dot or point as you curve a line, they are blue)
