Thank you very much for your kind suggestion. We have several functionalities to facilitate the reuse of fill settings in other shapes. Let me have a brief description and see if they are useful to you.
== Store fill setting as Theme ==
Right-click on a shape
Select Format | Fill… from popup menu. This displays the Format Fill Color dialog box
Configure the shape color
Click Add to Theme
Give the theme a name and confirm
You will see the color is stored as an entry inside the Gradient Color Theme list. You can then reuse this theme for other shapes. Notice that you can store only gradient but not solid color as theme. But you may, of course, select the same color for to and from color in order to store a solid color as theme.
== Set a color default to all shapes ==
Right-click on a shape
Select Format | Fill… from popup menu. This displays the Format Fill Color dialog box
Configure the shape color
Click Set as Default.
Select either Select as Default for %model_type% or Select as Default for All Shapes.
I will pass your suggestion to our developers for further studies. If there are any other comment or suggestions, please do not hesitate to contact us!
