Since project templates are source language specific, a customer with a lot of source languages and work options will quickly end up with a very large list to choose from (ex: customer with 10 source languages, who does translation, translation with DTP, translation with review, translation with DTP and customer review, will end up with 40 project templates), it would be good if selecting the source language would filter the list of project templates down to just the ones that match it.
Note: this refers to filtering the list of project templates at project creation; at the moment, even if you select your source language before displaying the list of project templates, it doesn't filter them down.
