ADDING A SPARE IN REVIT MAKES it 0 amps by default. About 99.9% of spares are 20A. Being able to set that default, even if Revit hardcoded it to 20A would be a big time saver.
Also it would be great if you could revisit the usability of panel schedules. you can't edit multiple cells at once, you can't copy paste, you can't fill, can't connect to excel.
