@andresmmera I've seen that you collect several xml-components in one xml-file, e.g. https://github.com/andresmmera/qucs_s/blob/e72389cb8908d1e4408b20f3eed937eee6ef92ac/qucs/Libraries/Lumped_Components.xml. Imo this approach has several drawbacks: • Someone can break the whole library by making one single xml-mistake • Difficult to seach for a specific component • Growing size of such library with component integration I would prefer one xml-file per component, and (if needed) several directories for thematic differentiation. What do you think?
