Hi! No worries on the wait. I re-did the grid, though, and I think it was easier to merge them into 10 squares instead of 15. This is how it'll look on computer and here's the mobile version. If you want more spaces, though, I can totally make 15 (or however many you want) out of this.

I could also have a lot of images for full-screen view and make a lower number for mobile use. Like have the full 20 spaces for a wide space but use the 10 spaces version for mobile space. Making the code will be a little more complicated and the visual won't have that effect when viewing the entry code instead of directly on the journal, but it could be interesting! It just all depends on how many spaces you want to play with. :) Thanks!
