Since H22 the way to set tool parameters as "Permanent Default" change... and just don't work.
Example to customize the polyextrude sop node :
Now we first need to create a node preset (named here for the example : "myPreset"), then set this preset as default.
First problem :
Then when call from radial menu, the permanent default preset as just ignored (it use the factory one).
Others problems :
Now when call from tab menu you can notice that both operators entry are here instead just the permanent one :
Note to dev : Please think as user that tape first letter and hit entry key as quick as possible. Now that's means extra step to select the right version of operator.
And when called the "PolyExtrude (myPreset)" from selection, it don't link the node and also ignore primitive selection.
Did I miss something ?
