I just have finished working on the veryfirst version of the "saveproject" lscript. It saves the Scenefile+all objects+all images into one folder (+relinking). This can be useful for example, if you are working from different folders and you want to sent all files together to your client.
You can download it here: http://lwtoolbox.com/content/saveproject.lsc (http://lwtoolbox.com/content/saveproject.lsc)
If you have any critcs, suggestions or ideas for improvements just let me know.
Hope you will find it useful
