Can't zoom in on side editor for incremental PDF

currently in the pdf viewer you can click the three dots on the top right and "split the panes". This allows one to jump into different folders with different notes, but this cannot be done with the incremental reading plugin.
So basically there needs to be a way to view document notes on the left "zoomed in" like in this example where I have a document for linear dependence and span, but cannot zoon in to that folder because it would exit the incremental reading viewer
there are other small things, but you did a great job James! I'm over the moon
