I'm also using the new Grid UI to overhaul Shattered Pixel Dungeon's journal notes page! The automatic adventuring notes, which record keys and landmarks, are now presented in a much more compact form! I've also added a few new landmarks, such as special floor types.
You might notice that there are a couple of other new things in this UI as well, more on that next week...

I went back and forward on this in development before settling on the more compact view. I do agree that this can result in reduced readability, but I felt it was worth it compared to making the player scroll a whole lot to access earlier floors. I made this choice partly because the lack of compactness makes the current list UI totally unusable, and moving to the grid's main goal is to address that. Using one floor per row would also be especially bad in landscape where there's roughly twice the horizontal space and half the vertical space.
Ahh, I never think about landscape. ๐
Perhaps adding separators as visual cues to help readability?
Please look at the screenshot again, there already are separators when two floors are on the same row. Separators on different columns seems unnecessary as there's already a new header that serves as a separator.
Oh, I see the vertical separators now. Maybe a 1 or 2 pixel padding would make it easier to see?
I feel like either vertical space or horizontal separators between rows, would better signal that you're supposed to read left-right, then up-down. With the current layout, my eyes are drawn downwards first and see Floors 10 โก๏ธ 9 โก๏ธ 8 โก๏ธ 6. Horizontal separators, for example, would break that flow and tell me to look right and see Floor 7.
