Well, I cannot even load it because seems you have too many tables and fields.
You are facing some limits.
The next rewrite will be the builder interface. Promise.
And Raphaël (for database rendering) will be based on the raphaël 2.0... Printable, and I hope maximum features...
This builder is based on MooTools and is going to its limits.
Promise a new interface will be released in future. For the moment, all I can fix or arrange are only things I will anyway need to deconstruct soon and this is the reason why it is ugly and I do not cure it too much. Because it will be 100% fully rewrited.
Please be patient.
If you absolutly need to see your database, I can reset the table positions manualy. Do you want it ?
