In Finale it’s common to select a couple of consecutive bars and then select “create simple repeat” from the menu to create – well – a simple repeat. It might be my muscle memory but I think it could be useful if the same would be possible with the repeat popover in Dorico, i. e. select a couple of bars, press Shift-R and type “repeat” to create a simple repeating section rather than having to do this via the Bars popover (I mean, it doesn’t have to be mutually exclusive, this could be an additional option).
Does that sound feasible?
