It’s lovely to see this, @Mohammad! I had been slowly updating a few of of my favorite Shiraz macros to use the more recent syntax and was just pondering attempting the same for dynamic tables, so this is excellent timing.
I haven’t had time to do much experimenting with Shiraz 3 yet, but I did notice that while your Migration tiddler notes that “Details macro uses the new $genesis widget” (great idea!), this change doesn’t seem to be reflected in $:/plugins/kookma/shiraz/procedures/details yet.
