It's a little laggy when I'm typing, I keep notes for my whole class, not one file per lecture so the files are decently big. I have found all markdown editors with live preview have this same problem as they redraw on every keystroke and this is fairly slow process with a big document and slow computer. My note taking laptop is not very powerful. This program looks great and I really want to use it, so I may need to start creating a new notes file for every lecture and then using a script to combine them later and export to PDF.
