Just porting my records over from my original Mammals of the UK taxonomy to the new Mammals of the United Kingdom and Ireland checklist from the World Mammals taxonomy and have spotted something that might be a useful change to implement.

On the replace species tool, there are radio buttons to select common or scientific.

It would be useful to have these stay as a previous selection, so they don't have to be re-selected each time (a total of 6 key-strokes if you want to use scientific names for both sides of the swap).
