I like that you can have custom fields to add your own tags or keywords for searching in specific areas - such as technical drawings! The layout looks very cluttered sometimes with too many tabs/features open at once which makes it difficult if there are multiple people involved editing within one file type (like an RFP). Also having all features available is overwhelming so far since we don't know what each feature will do yet until someone uses them first -- not sure how well this works during development? We're using metaltrace primarily because our main products require drawing files but also need text content.
