Proposal: Enable SelectionCheckMarkVisualEnabled functionalities on ItemsView control

Summary

SelectionCheckMarkVisualEnabled should be added to the new ItemsView control as a property to match the functionalities offered by ListView and GridView controls.

Rationale

• Right now, when using ItemsView.SelectionMode = Multiple or ItemsView.SelectionMode = Single as the selection mode on a ItemsView control, the control imposes a checkbox as the selection indicator. This limits the developer's capabilities of styling the control to better fit his needs.
• Other item containers already have this property defined on them, and it should be a good practice to have all item containers at a certain level of feature parity.
• It is not acceptable to use ItemsView.SelectionMode = Extended to bypass this limitation because in certain cases its contradictory to user's expectatives of the components (As a user, it's easier for me to click on the items to toggle on/off their selection status instead of having to rely on Ctrl+Click) or it requires more code by the developer to mimic existing logic (If I wanted to only support selection of one element, extended allows multiple selection of items and thus it would require a lot of code-behind to limit the addition of new elements to the selection bucket).
