We had seen the CSS masterclass app and what it can do. Currently, CSS scripts are hidden at the multiple KPI object but this great facility should be configurable at the dedicated segment under the app to allow developers to beautify the app using CSS scripts. It can be applied at the app or sheet level. This should be made variablized (fx) as well. Hope this is considered and i can see this as the game changer for people to move from QV to Qlik Sense with the flexibility to change the UI. For CSS, it will be best if Qlik can expose the object settings to allow easy reference. A help guide is preferred online. My ask summarized below:-
1) Create a dedicated CSS Section at App Level for applying style change to entire app or selected sheets
2) Allow CSS Section to be variablized (FX)
3) Create an online help guide to allow developers to expose Qlik Object to apply the changes.
