Just some thoughts for the restless coders... I have to admit, i am not a coder, but i can read some code at least. Though I have to do some PHP and JS modifications from time to time – but its definitely not my daily job! The K2 modal window behavior and its content plus the button combination reminded me on:
NoNumber.nl 's AdvancedModuleManager
That seems very close to the optimal behavior. You should have a look at the code, or even better: Contact Peter van Westen. I guess, he could be a great help!!! !!!
