I'd love the ability to draw several generic icons on decals, for example the icons related to categories of materials such as salad greens, hard-metal, soft-metal and so forth.
That, plus the icons for each attribute and the icons for the base bars i.e water, energy and health.
The process could be as simple as simple as right clicking an empty parchment and an option for "Draw Generic Decal" with then a small list to pick from.
