Hi @azmawi,
We’re currently considering our future plans for OCS – in the meantime, I’d suggest Googling around for OCS installations to see what kinds of modifications have been done to change the presentation. It’s not a particularly modern platform with respect to theming, which is one of the things we’ve addressed with OJS 3.0 but haven’t done with OCS yet.
