Higher Level Math and Graphing

I am a chemistry student and just recently got my Boox in the mail. Absolutely amazing. Everything I was hoping for and more.

My only issue is that STEM features seem to be a little lacking. It's entirely possible that I'm missing some big things but here are my issues:

Handwriting recognition for mathematics and chemical formulas doesn't seem to work, sketched graphs come out wonky and scribbly since the screen is so sensitive (my biggest frustration by far,) I can't seem to edit or change lines easily when dealing with graphing.

Is there a "smooth lines" feature or something where I could just tap a line and have it automatically smooth out? Just anything to make graphing fun and aesthetic...

I am willing to use any app at any price to make this happen- I just absolutely need this function for my STEM classes!
