One of the sweetest improvements to me and one of the most unheralded is the improvement to the Page/Layers Gallery.

Previously to select/deselect either a layers visible and or editable state you had to click on each layers state individually or shift select between layers.

This is no longer the case, you can just slide your mouse over the icons in the layers menu to turn them on or off.

A fantastic improvement! Well done Xara.
