Fields like manufacturer benefit from not having aliased names (ie: "Digikey" vs "Digi-Key") Implementing typahead on these fields would reduce the occurrence of this.
The Footprint Ref/Library Ref fields which allow downloading of the SVN models are broken if the models don't exist. Link should route to a friendly error message, or be grayed out, rather than ending at the exception page.
To reproduce:
Create a new part, and give it a bogus footprint ref and/or library ref
Go to that part in the parts table and click on the link to download the bogus file
Profit.
The UUID is super important, but should be hidden most of the time. Still, the ability to see the uuid for a certain component is sometimes useful, so this feature needs to be exposed in a way that is unobtrusive.
