USM or Kanban boards with Sticky Notes instead of cards

I looove me some USM or Kanban boards. The one feature I struggle with is the formatting of the cards inside of them. I would love to be able to have Sticky Notes inside of a USM or Kanban board. It would be much more legible.

Yes. It is troublesome to zoom in and out and in and out to read the title and the content of the card. Especially when the font size adjustment is different when you are zooming in vs zooming out.

Another advantage of sticky notes is you can use a fill color to fill ALL of the note instead of just the border around cards.
