Below is a design for a comment @promag made here https://github.com/bitcoin/bitcoin/pull/16432#issuecomment-513814481 about having a toggle option for the privacy mode proposed in the same PR.
Rather than the current user flow of checking/unchecking Menu->Settings->Mask Values users can quickly click the icon to toggle privacy mode on and off resulting in a cleaner flow / less cluttered menu options.
Tooltip - this should not pop up instantly as it does here but rather after a ~750ms delay (same as WindowsOS, which styling this design follows). Figma does not allow an instant delayed animation - it really should.
Why would a user want to have this feature toggled faster?
A hypothetical scenario would be if the user had the GUI open and someone walked behind them they could quickly conceal their private information by clicking this rather than the current flow which would take a second or two compared to milliseconds clicking the toggle.
Why V1? Whats next?
This version stays within the scope of https://github.com/bitcoin/bitcoin/pull/16432 by only concealing information in the overview section of the GUI. Having privacy mode extended to the other menu options (e.g. concealing addresses / transaction hashes in transactions menu) is something that could be explored in a further version of this. The toggle would need to be moved to a global section for this, either in the bottom or top menu.
