Custom icons for items and folders/collections

Icons need some work for sure. The current problems are:

  • they are assigned automatically, at least in browser plugins. You need to readd the whole record if something didn’t have an icon or the icon got removed.
  • they are very slow at times, I assume it’s because they’re loaded from URLs and not cached?
  • not sure if customization is something I’d use, but at least disabling them for certain records, not only overall, would surely be welcome
