Hello @maniron ,

you can access sequence module any widget by using getModuleWidget in python console  
Here’s example:  
slicer.util.getModuleWidget(“Sequences”).findChild(“ctkComboBox”,“ComboBox\_IndexType”)

There is no need to access module GUI widgets. You can set up a proxy node by calling [AddProxyNode method of the sequence browser node](https://apidocs.slicer.org/master/classvtkMRMLSequenceBrowserNode.html#aba16a856688831e670c26c9f4cd7fc34).
