It would be great, if we could enhance patron attributes so that you could record a piece of data for each patron, based on events. For example, what if you decide you want a timestamp for that last SIP login? Or maybe you want to know when they last logged into the OPAC. It would also be great if there were counters that could be associated with an event. How many times has the patron renewed their account, or how many times have they logged into SIP or the OPAC.
