Hello. Currently, you can only switch between a rectangular and an isometric grid. There is no way to add a custom grid, but it is an interesting idea. Is there a software that lets you do that so we can take a look at how it would work? Thanks!
You want to edit the size of the grid? You can do so under the Edit menu, Preferences and clicking on "Canvas" on the left side. You will find options for the grid cell size there. For more information on the grid, you can also refer to this page: https://orama-interactive.github.io/Pixelorama-Docs/user_manual/user_interface/c...
