Following a topic I raised earlier would (when they have nothing better to do of course) consider adding the ability to remap the keyboard shortcuts either as a "as well as" or "instead of". I realise this requires a few new chunks of code (save as, load, reset to default, consistency check etc). In my case adding "s" as well as/instead of "z" to zoom would be good and when on laptop to use "END" as well as/instead of "DEL" to delete.
