Improve keyword string splitting mechanism
When you put a string inside a keyword field/variable, the system split the string in separate keyword entries at each space or comma in the string wich is simply horrible to handle.
You have a dirty workaround solution by putting your string in a text variable concatenated with quotes and then assign the text variable in the keyword field.
Plus, currently, if there is quotes inside the string itself (for example, french words and/or expressions are using quotes), your trick with the intermediate string variable doesn't work at all...
You should add the possibility, in the data assignations inside the workflow designer AND/OR directly at field configuration, to specifiy the save mode "KeyWord mode" or "String mode" for example.
This way we will not be forced to put a string inside a variable concatenated with quotes at each keyword assignation (seriously, that's a crazy aberration... This should be managed natively)
