Comment 1 for bug 1454516

Mode of use:
- Open the customiser dialog from the menu 'Edit>Customise interface'
- Check the tools you want in your customised UI, by default only the wheels controls are checked
- Press ok to validate customised UI and save the sketch: at next load time of the sketch you will have a customised UI
- Press Cancel to not validate customised UI, however at the next save of the sketch, yours preferences are saved but you still have the default user interface.

From the sketch xml file (.fgeo extension) you can inactivate customised UI by setting to "False" the attribute "custom_controls"
