It would be conveniant to have the oppurtunity to open a specific feature in a specific webmap with an URL.
Right now it is possible to open a webmap and include a search in the URL. But you can´t open a webmap with a features ID or something that is unique.
It would open up many new ways of working - for example open and edit a feature from an exported shape, csv or geodatabase or open and edit a feature in an webmap from Collector. It would be even better if you could open a webapp from Collector with a specific feature.
