Ability to Copy/Paste styles
It would be much easier to customize the look/feel of a form if one were able to either copy/paste style from one control to another, and/or the ability to select multiple controls and modify an aggregate of their shared style properties at the same time.
The scenario is an item view with 12 controls paired with labels. The labels all need uniform styling. Currently, one has to style each label individually with the same settings to achieve the desired outcome.
