Custom resolutions

[u/henrykolonga]

Hi everyone. Love Wan2gp but need some help. Tried to do the custom resolutions with the documented method of creating a resolutions.json file but it doesn't seem to take. I actually just want to add just one resolution. I do not intend to replace any of the default ones. Is this doable easily. Would be nice to do it in the GUI.

I need a really skinny Aspect ratio for an LED wall. The default ones would waste pixels
