Finally seeing the light with metadata, Calibre and Koreader, many thanks to all your inputs so far!

Some quirks still baffle me. For instance, in Calibre, I added tags to epubs that are already on the device, and I'd like to update just the metadata, so I can browse by tags on KoReader with the new metadata I added in Calibre.

Via Calibre, I update the cached metadata on the device, and the calibre.metadata file on the device updates (changed size and date), but after disconnecting from USB, KoReader doesn't recognize the new tags in the books that are already on the reader, just in new books I upload that contain the same tags.

I re-start the device and KoReader, but still, new tags don't show up. In the +Menu on KoReader, I update the cached metadata of all books (took 10 minutes for 2,000 books). Then I reconnect the device via USB and mount it in Calibre. The calibre.metadata file updates (just changes date, not size). I update the metadata again in Calibre and I disconnect the device again, but KoReader still shows the old tags.

Do I need to re-upload books when I change their tags or can I just refresh a cache on the device to make KoReader see the new tags in a more quick and easy way?
