A small bug, when scrolling up to the top of a document using the arrow keys, the line you're on is two lines above where the visible text starts, leaving the top two lines hidden until you scroll with a mouse
(This is minor but still an annoyance)
annd not sure if this is a bug or not but you cannot close all documents with ctrl+w, the last one stays.
(PS this app is really nice and I use it all the time, thank you. I put no pressure on it being fixed as I know you have other more important things and did just update it recently anyway :)
