Another possibility–and I’m just spitballing here, because it’s Saturday morning and I haven’t even finished my first cuppa–is to change how we get from Observation to Identify entirely. This would not only solve @arboretum_amy’s request but make it easier (and more obvious to beginners) for anyone to switch.
Add Identify to the option buttons to change between Map/Grid/List views at the top of the page:
Identify is really just another way of viewing observations, after all.
The only difficulty I see, off the top of my head, is that it probably would be a bit more complicated (on the programming end, which is not my thing) to modify the Identify view in a reciprocating manner. Which is not essential, but is desirable in keeping with my point about Identify being just another way of viewing.
