Disable Background Data Preview Refreshes Global Option
Currently there is the option to disable background data previews in the "CURRENT WORKBOOK" section, but I find myself having to do this in every single workbook to prevent PQ from keeping my processor pegged out at 100% constantly. It would be great if there was a global option to disable these so there was no need to disable on a per-workbook basis.
See this article why this can considerably slow down your queries: https://blog.crossjoin.co.uk/2016/12/05/power-query-power-bi-and-the-allow-data-preview-to-download-in-the-background-option/
It drags your laptops battery empty as well!
Or change the default-setting to "disabled".
This would also show a heart for PowerBI newbies who are even not aware of this setting and are wasting precious time with unnecessary wait.
