1.0 has an interesting layout issue that interacts with scrolling. Opening a section, I run into notes that are not aligned on the left edge, where some are shifted slightly to the right. When scrolling, they will pop back into alignment. Only seems to happen when the project is long enough to be scrollable.
And speaking of note layout, it would be nice if there was a way to set a max width for notes. Going full screen on larger monitors (iMac 27”, or a 34” 21:9 monitor) means the text gets wide enough that it is hard to read. Bear addresses this fairly well, but maybe keeps the line width a bit narrow for my tastes.
