From what youāve shared in the past it was due to having tricky āDefaultsā for an dashboard layout of an entity. Maybe thereās other reasons not shared. But having a dashboard layout (along with single and double columns) would be really amazing. It would start blank, and would just another entity view layout. No need for defaults.
Iām just worried you are making the same mistake you made with documents in the past. Native documents vs. Documents database - #5 by mdubakov
Personally Iād prefer taking the time to do it right, than rushing to do it in a way that will be harder to fix later.
