To note, I’m not on lineage, but I set Tasker up to display little dots depending on the notification. Orange for a notification, blue for a reminder, and red/yellow/green for 15% battery, 30% battery, and 100% battery, respectively. I have the dots also combine when several of these notification types are present at once.

You can see them in this screenshot. I currently have reminders and notifications. They look like big blobs on the screen, but I actually have a hole punch camera, so it actually creates a ring around that in reality.

I’ve definitely imported a custom font on my Note 20 in the past. Whether that feature is still alive in the most recent One UI versions I’m not sure I suppose, but it was possible, just incredibly backwards and convoluted. If I recall, I had to download a font file and then put it into a very specific folder for the UI to recognize it
