I am looking to utilize the new Web Editor to give easier access and functionality for my co-workers. I am wondering if the attribute pane and table will find easier use by adding a way to open it from the selection pane. Also, I noticed you can only open the attributes if the selection is inside of one singular feature layer. Will this ever evolve to be able to choose from your selection which feature you would like to have the attribute tab/ Table open? Another thing I have noticed with some shortcuts is that there isn't one to open the scroll tool. While I noticed holding the spacebar will allow moving about the map in an edit section, it seems to get sticky and sometimes messes up my selection.
Web Editor only support the ability to perform bulk attribute updates within a single layer. Expanding this to support bulk attribute update cross layer is on our roadmap, but it hasn't been assigned to a future release.
