RSU--Portfolio View????

Do you ever sleep, @Gary R?

RSU stands for Restricted Stock Unit. These are often granted to employees as part of their compensation.

RSU is not a column in the Portfolio views, it is an undocumented new built-in Security Type. You have grouped your Portfolio view by Security type. When you create an RSU, the security details have a setting "Base security"

Note that there is now also a security type and Asset class of "Crypto". 

There are also some columns in the Portfolio views that I do not recall seeing before: "Unvested market value", "Yield on Investment (%)", and "Yield on Investment (Estimated)"

Presumably these are all in preparation for providing support for Crypto and RSUs and other changes to the Portfolio views.

The Unvested I am less sure about, but the two Yields have been around a long long time.  The (Estimated) is using the user-supplied 'Est Income' field from the security details.  

The RSU and Crypto types are not in my R37.67 install.

@Gary R  It has been an irritant for me for a long time that Security Types get listed as your RSU shows when there is nothing held of that type.  I find if I change the Group by to something else then reset it to by 'Security Type' the extraneous types do not appear --- at least not immediately.  They will reappear if I make some other unrelated change in the file. 

Glad that fixed it.

BTW I changed your post from an Idea to an ordinary discussion. Ideas are generally for suggested product improvements, not for questions.
