Rob Tonfotos supports writing face regions with names into metadata, it is just turned off by default for performance reasons. Here’s how you can turn it on: https://community.tonfotos.com/d/535-version-1105-saving-person-data-in-xmp If you do this, other photo management applications will be able to read this information. However, if you are talking about seing properties by Windows Explorer, then no, it has limitations to what it can show. It can show tags, captions, comments (all those are editable in Tonfotos), but it cannot show faces and names, unfortunately. But other applications can.
To marking up boats and other stuff like that, you can use Tags. Just right click on the photo and do “Add to..”->“New tag…”. Windows Explorer reads tags added by Tonfotos.
Tony As far as I know there isn’t a way to rename photos in TonFotos but right clicking in TonFotos and Go to Folder works for re-naming photos.
You are right, we don’t yet have functionality for renaming. This is because we don’t think that using filenames is rigth way for storing such information. Image metadata offer much more convinient way to store all what you want to save about image: date, location, caption, comment, tags, people, and so on. Tonotos if focused on using those for managing information about photo content.
