When a user needs to decide between various fields to add as a column to a view, it may be helpful to have the mouse over text to appear for clarity and definition (especially if there are similar field names). On the form, the mouse over comes from the description of the respective field. This be displayed on the Edit columns, add columns, the view itself and maybe even in the edit filter menue when you filter for some attributes, this would be very helpful to get the definitions 'right under the fingertip'.

Possible use cases: Eg. 'Number of Employees' --> Number in terms of FTE (revenue by FTE)? Or maybe 'headcount' for e.g. license plans which often require 2 full licences for 2 people sharing 0.9 FTE at a 30% and 60% employment plan?
