Default view(color,size) of nodes in a graph

I am new to neo4j and looking to have a customized neo4j UI, for e.g have a customized default color of all nodes as Blue and the size of node to be as bog as possible.

I have downloaded this
GitHub - neo4j/neo4j-browser: Neo4j Browser is the general purpose user interface for working with Neo4j. Query, visualize, administrate and monitor the database. and tried to see any config file to achieve the above. I don't want to go to the option provided in the node selection every time and change.

Where can i find this configuration or any developer manual available which will help me achieve it?
