congrats on the launch, linking figure/element numbers to is a feature i've had on my list of features of things i'll never build for awhile. also, have recently added thumbnail search results (think google patents had this ages ago, but has since retired it if they did) and a smarter weighting of keyword search (e.g., filtering out noise from sections and boosting hits in claims/abstract/etc). would love to help out if needed (contact info in profile)
