Hello!

Is it possible to use frontend extensions in OpenKM professional? For example, to create new button in toolbar.
As I understand, to use it in community edition, I need to compile source code of community edition together with my one code.
But source code of prof edition is not available.
So how can I create new button in professinal edition?

With professional edition you should talk with sales & marketing OpenKM guys for it and will try to find a solution for you. Could be add directly your extension on a patched OpenKM version or integrate yours - specific extension - with general purpose one.
