I've revised the ChangeColor plugin UI (see the attached screen shot).
Undo is still unimplemented, I would still advise you to backup your models before using this plugin.
The version number has changed from 0.2 to 0.3, so you will need to remove the old jar and replace it with the new one. I've uploaded the jar to the normal place: https://sourceforge.net/p/sweethome3d/plug-ins/14/
Changes:
- Swatch buttons on the Colors-in-use tab might now fill with color on all platforms (maybe).
- A list of items using the selected color is displayed to the right of each chooser and updates when a color is selected (this is in addition to the hover tool tip)
- A count of the matching items of each type is displayed in the list of items and in the tooltips.
- On applying a change, the to-color becomes the new from-color.. This allows for repeated attempts to pick the right color.
- I fixed a bug where if an a material had a texture, but the material also had a default color, then the plugin attempted to change the color.
