Select shapes by master
It's possible to select shapes by type (e.g., guide, connectors) and by layer, but it would be very helpful to be able to select shapes by Master in a similar way. In conjunction with Shape Replace, it would be a quick means of replacing shapes in bulk.
Also to be able to select shapes and exclude the connectors, to be able to e.g. change the size of them all at once, which isn't possible if connectors are selected as well.
