An option to mask/blur every absolute value within the app, leaving only % values. Possibly with an option to mask these as well.
Should work in all tables and force the charts into % mode.
Useful for screen sharing the whole portfolio, when numbers should be private.
To make it even more useful, double-clicking any masked number could reveal it, so you can pick exactly what you want to share with others. (This one would possibly not work with charts)
