DMX Output window

It would be nice if the DMX Output window responded more like a spreadsheet. Currently I can select a whole column by double clicking the column number. I can then test/set to artnet/set to hognet. And Set fills the column with a value. However, double clicking a row number brings up a text entry box with the row number that changes nothing. It would be nice to be able to select rows to test/set to artnet/set to hognet. Also handy would be the ability to click on the top left cell labeled "Addr" and have that select all cells. And one more thing for this window when copying and pasting values it would be nice if the pasted values wrapped to the next rows, i.e. they were offset.
