I've noticed a few bug reports and comments on the developers mailing list recently about the confusing/buggy behavior of the footprint filtering in CvPcb. After using CvPcb while testing my NETLIST_READER changes, I think I understand issue. CvPcb uses three toggle buttons to set the footprint filtering to limit the number of footprints in the footprint list window. One toggle button enables/disables the filtering and the other two allow you to select filter by footprint filters defined in the netlist and the other by the footprint pin count. There does appear to be some buggy (or a least some confusing behavior) with the filtering selection. I propose that the enable/disable button be removed and the two filter type toggle buttons be used to select the filter criteria in a binary logical and fashion. In other words:
When both buttons are off, show all footprints. When the filter by netlist filters is on and filter by pin count is off, filter by netlist filters. When the filter by netlist filters is off and filter by pin count is on, filter by pin count. When the filter by netlist filters is on and filter by pin count is on, filter by netlist filters and pin count. One other behavior that might be worth changing is when there are no footprints that meet the filter criteria. The current behavior is to show all of the footprints. This may add to the confusion when the user expects filtering and sees that none of the footprints are filtered rather than an empty footprints list. This makes sense to me. Please let me know if I'm way off base here. If there are not objections, I will add it to my list.
