The evolution of the native Button chart and its added features for reload data etc. has been a huge windfall. So much so it's the number one extension used throughout our enterprise environment.
Could Qlik also add "Export" as an action to remove dependencies on 3rd party extensions such as Stefan's sense-export or Vizlib's button with the export action? Both of which are not currently working in Qlik SaaS.
The addition here would also need to be functional in mashups hosted on external servers as well, because of a Qlik SaaS environment.
