Make it possible to use a database table where keyword weights are already stored.

Try setting an optionSplit property on the tagWrap rather than using the separator property

In the flexform, put a message along the lines of “Please select a table first” in the referenceFields as long as a reference table has not yet been selected

Transfer some of the ideas for the use of hooks to the plug-in configuration (minimum length, minimum weight)

It might be useful to be able to use a stop word service in the tag cloud, but such a service has to be developed first...
