Ideally your systems should have an identity, not really look the same. Also, I think the system should use more CSS, to make it easier to change the system's layout. Version 1.1.8 still uses a lot of hardcoded color settings, a few fonts, as well as too many tables (they do not display correctly in different languages).
Another suggestion I wanted to make was regarding the Review/Editing area. I believe that the interface should display only the task necessary to be completed, or show the user that it has completed the tasks above, so that there is a visual feedback for the user. This could be accomplished setting a $_SESSION variable for each table, or changing the CSS of the table to a class or id completed.
We have been providing many trainings for editors in Brasil, and they have become confused sometimes, because the system always goes to the Review of the submission, even when it is in the Editing process.
thanks, and hope that vrs. 2.0 is coming soon!!
