User-controlled "Defer layout update" switch in Custom Report
Some users know exactly what they want to select when using Custom Report, and they would benefit from "Defer layout update" option being enabled, because everything would work faster for them. On the other hand, some other users are exploring the data, switching dimensions and measures on and off to get to the bottom of the problem. Asking them to click the "Update layout" button every time would make everything slower for them. Of course, some users are in both groups, depending on use case. :)
It would be nice if there'd be an option for the end user to toggle the defer layout update mode themselves, depending on what they need at the moment. If screen real estate is a problem, maybe something like "Update layout and don't ask me again in this session"-button would help many users.
Thanks for listening!
