I use Divvy as it was the only one I found that had the ability to scale up to larger number grids. https://mizage.com/windivvy/

You can see the rest of my ergonomic aids here: https://twitter.com/mbuckbee/status/1463598464252665866

- Kinesis Freestyle split keyboard tented and then tented even more with slanted yoga blocks

- 4K monitor/tv to show multiple screens to reduce alt-tabbing

- Magic trackpad mounted on a cellphone stand on the left of my keyboard (I'm right handed). This lets me use my non-dominant hand and requires less arm movement.

Amazing, thank you for sharing!
