The right column will display two tabs: "Elements" and "Behavior". (no icons)
- Elements tab is displayed
- Behavior tab is displayed with element selected in Editor.
=> Check if an hover state on the element is necessary (a border, a background, a pen icon) to make user feel that something will happen when clicking on the element
+ last minute thought: it can be useful to add links to elements catalog documentation
- a link in each nuxeo elements catalog row (to Core Elements, UI Elements and DataViz)
- or a link in each element ?
See screenshots. I've added blue links but it can be an icon, I let you be creative on this if you think that the documentation link is useful.
