The default behavior when saving a new model used to be “save then reset the form”. That was pretty annoying 9 times out of 10, so a recent change made for a plain save function, and a split button with a “Save and Close” option.
I’d like to see the old behavior come back as an additional “Save and Create Another” option (or something similar), for cases where users are doing repeat data entry.
I’d also like to see some keyboard shorcuts for the different save, toggle, and close options. Folks who do a lot of data entry don’t like to switch between keyboard and mouse. It’d also improve usability a great deal. The shortcuts should be listed in the docs, as well as title/bubble text, aria tags, etc.
