Thanks Tihomir.
I successfully installed the new version of the designer and the button is there.
Unfortunately, I could not install the new guvnor yet (git has problems with the proxy). Until I install guvnor, I thought I d play with the new designer.
However, if I click on the new "generate task form template" button, it opens a new browser tab with the following URL, which is completely empty.
Since the designer is loosely linked with guvnor, I guess the button problem is not linked to the missing latest guvnor version.

No task forms appear under "other assets and documentation".
I tested it on the evaluation example in Firefox 3.6.18 and 5.0.1 as well as IE 8.
IE 8 did not even open the designer:
