I cannot see all the list items when needing to see the headers of a board. >> Resize, drag or move the screensplit from the board-view

Hi, (see image included)

I have items (nodes) that I want to categorise by dragging them in the respective list of the board (table). However, I can't see the items at the bottom of my list, while seeing the "headers". 

Right now I scroll... a lot...-but this is not desirable in particular when doing a share screen (then I switch to stormboard. another tool. However because I find workflowy ideal for diving. in ideas after the categorisation I then would need to type things again.).

It would be lovely to be able to drag the screen split (blue on the image) or to scroll only the bottom part...
