It seems palette related bugs are back as of version as of 2022.33600 for Mac OS 13.4.
- cannot add a tox file to a custom folder in the palette by drag n drop from the Finder
- cannot delete a custom folder or component. Right-clicking > Delete folder/component appears to delete it from the Palette - but refreshing the folder brings it back.
- dragging a component from one custom folder to another - copies it rather than moves it.
