Hi @jagerwin, welcome to the iNat forum! The “Add ID” option - on the main/Info tab of the Identify pop-up, is for when you already have a good idea of what the organism is. You just click Add ID (or, pro-tip, tap the i key) and start typing out what the name of it is. Press enter twice and move to the next! That’s the quick way.
The Suggestions tab, also known elsewhere on the site as “Compare”, is for when you want to use some filters or tools to help narrow down a potential ID you have in mind. For example, you might know it’s in a particular family, but want to see what all the species are that have been recorded from the general area of that observation, just to check to see if it could be something closely related. I use the Suggestions tool more when I’m branching out beyond my primary areas of expertise.
You would type in name under Taxon, or sometimes it’s already filled in based on the observation’s IDs. This automatically shows observations of those taxa in the approximate area of the observation in question:
Then you can show whether you want to restrict the search results to only research grade observations, include captive observations, compare to a checklist for that place, etc. This is also where you can use the computer vision tool to show taxa that are visually similar to the first photo on the observation.
You can also broaden the place filter, to show all of Florida instead of the particular county:
