Hi Didem,
Thanks for posting your idea on how to improve SDL TMS. Usability is one of our key focus areas with the product and we've already taken some steps to make it easier to create new jobs using the new SDL Managed Translation functionality. We will be bringing a similar experience for all SDL TMS users in a future release although we don't, at present, have a firm release date. You can find our more about SDL Managed Translation by visiting this link:
