In the "new translation" dialogue box (screenshot attached), it would be very useful to have a checkbox or other simple method to remind the translator that they're able to publish to a sandbox - where they can then continue to work with the wider variety of editing tools available in the normal editing environments before publishing to mainspace.
I realise that this is already possible. You just have to specify the destination as [username/article title] but it would be helpful if this was made an overt option. e.g. by having a "save to a sandbox" button. When clicked, all it would do is change the destination "translation title" to append [username/ ].
Having this simple function would remind people that they don't have to get it all perfect before publishing, and also help to defend against criticisms of people publishing un-translated articles straight into mainspace.
(please advise if I've not created this feature-request correctly!)
