Hi Cassiopeia,
DropForeColor and DropBackColor just the example code, it not use in editor by default.
If you want to test it, please follow the steps below
1. open file "\cuteeditor_files\Configuration\AutoConfigure\Default.config".
2. Find section below
<item type="dropdown" name="FontSize" width="60" text="[[FontSize]]" command="FontSize" />
3. Add the section below under the section above
<item type="dropdown" name="DropForeColor" width="60" />
4. Now, you should see the section in the toolbar
Regards,
Ken
