Hi pablo78
All the behaviour you describe (the little arrow on the right, and tag value proposals) are indeed standard features of Explorer, with no dependency on File Meta at all. File Meta merely allows you to add tags and other metadata to file types where Windows does not support this out-of-the-box. My ‘for some definition of recently’ is just an indication that I don’t know the rules either: I too have noticed that not all tag values are immediately added to the list of proposals - maybe there is some background processing involved.
If you or WFreude would like to try my prototype tag viewer, you would be very welcome to do so. To give you an idea of its functionality, it looks like this:
Image may be NSFW.
Clik here to view.
The panel on the left shows a hierarchy of tags, and the panel on the right shows the files with the currently selected tag. The path at the top is the root of the folder subtree that contains all the tagged files. The idea behind a tag hierarchy is to support tagging at different levels of generality, so, for example photographs might be tagged using a country/city/location hierarchy. Then tagging the photograph with a location would also make it findable via the country containing the location. Files are tagged by dragging them onto tags, and tags are organised into a hierarchy by dragging them onto each other.
If you’re interested, let me know, and I will send you a private message to set up an email contact that I can use to supply you with an installer and a more detailed description.
