View desktop TaskBar: Help and preferences switches are disabled in code

[bwbohl]

The help and preferences buttons are deactivated in the code:

https://github.com/Edirom/Edirom-Online/blob/9121944b02f86ec178e9547b9334e0ee29f9a4c1/app/view/desktop/TaskBar.js#L76

According to git-blame, this was done 10 years ago.

Does this mean we deprecate those functionalities, or do we want them back and updated?
