Feature Request Samsung Notes

[LisaDJ]

I love working with with Samsung Notes. I would like to have some little features added though. 

1. The top bar can be adjusted, so I removed some things I didn't need, but I would like to be able to adjust the number of colors (now there are 3). 

2. I'm working with the pen and I can choose the thickness, but I would like to be able to draw dotted (and other kind of) lines since, when I try to draw dotted lines, it's not really dotted... It would also be nice if I could draw a square by drawing from it's left upper corner to it's right bottom corner. 

3. I would like to be able to type some text and then move the text around. It would also be nice, since I'm an Informatics student, that I would be able to add code (snippets) and math equations (LaTeX maybe?).

Thank you!
