Hi Lars,
Deds classifieds has the UI for this from what I remember. It also has tcl procs etc. to manipulate cr_keywords. Having cr-ui-chunks would be good. Why not just some widgets package? Maybe I can migrate the bcms-ui stuff on that? Since its CR why not just create a widgets dir on CR?
At anyrate once you have this in place, I can chalk down one less to do for bcms-ui stuff :)
