hehehehehe sure, no problem
ok, so this is SteamWorks layer on/off like @PieMonster asked for
Front of DVD box:
StemaWorks off
StemaWorks on
Same layer turn on and off logo on the spine...if the layer is off, logo is hidden on front and spine:
SteamWorks layer on disc plate share design with other platforms (Uplay and GfW)...when it's off, Steam is dominant logo...
and now for the rest

@ Kexikus had an excellent perception that steam logo wasn't centered on the spine (and on other templates where it's shown in that manner)...that is fixed now on all templates (DVD Spine, DVD Insert, Disc Plates, Jewel Case Front and Jewel Case Multi)
Example of DVD spine:
...and also told me about discussion here on forum for the direction of Jewel Case sides...that is now fixed so they are going in same direction...example shown with SteamWorks layer off and on:
...and since I was never to happy about steam only faded boxes design, it looked a bit cluttered, i thought maybe those steamworks boxes would be better, more subtle...so this is how it looks:
That would be the changes I've done earlier, and sw boxes I've done like 15 minutes ago

...and would like to thank both of you guys, PieMonster and Kexikus, for helping me make this template
