Sort:  

Yes, I have tried to imagine how I would sort and track all of the entries. I'm sure you will find what works for you. I think Juliank uses tags for each topic, a more granular way of sorting. All the best to you Diane.

Thanks! It's easy enough with the one tag, because I would not open the thumbnail for a building if the theme is animals etc. @jamtaylor who has doing this for a lot longer just uses the one tag, but he does have a bot and requires the heading to be specific. I'm not nearly at that point yet. LOL!
