App for working in big project

Try

import pivotpy as pp 
app = pp.VasprunApp()
#Tweak Global settings accross all project.
app.cache_data = False #Or True 
app.ibands_kws['mode'] = 'bands' #Or 'marker' 
#Display App 
app.show() #And interact with GUI to work for you

May not work in Google Colab Online.
