1. One requested feature is the ability to view any plates that were chalked "in violation" during a given time frame. For example, say the free parking window is 2 hours. If an officer chalks plates for a 4 hour shift, the admin wants to be able to view a report of any plates that were chalked more than once, more than 2 hours apart, at the same location, during that shift. Comparing this to the violations written would let them see if any opportunities to write a violation were missed.
2. Another request was for a report of plates that had been scanned during a certain time frame, with useful information such as previous violations. For example, if an officer chalks plates for a shift, the admin can pull up a report and see what plates were chalked during that time, if they had any previous violations, etc. It sounds like they're suggesting something similar to the LPR Events page we have already, just with more useful information immediately visible.
3. Another request from further back was to have more visual feedback in the app when a plate is chalked in violation. Currently, there is small text saying "chalked X hours ago, Y meters from this location", and audio feedback (a buzzer sound), but no visual feedback when chalking manually (I think when using LPR cameras there is). In addition, currently the feedback only applies to time, not location. It would be more useful if there was visual/audio feedback when a plate is chalked "more than once, more than X hours apart, AND less than Y distance from the same location".
