The attributes of a component can be manually modified by using the built in grid in the library manager.
An improvement to this would be the ability to export and then reimport the value fields to a csv file. The first column of the exported CSV would contain the component name followed by CSV attributes. The first record of the CSV file might usefully include field headings.
Once exported this file could be modifed in Excell or other spreadsheet and changes made.
EZPC would then have a further button the reimport the changed CSV file and using the component name as a key field update the attributes as described in the file.
At the moment it is possible to cut and past from the EZPC lib manager grid but the component name cannot be extracted.
This make library maintanence more difficult than it could otherwise be.
