Yes, I had some ideas and started working on it but I am kind of stuck. I 
still have to evaluate some things before I can proceed. Current plan is to 
import basically every bit (*) of metadata into the db (so it can be used to 
find images which wouldn't work if it gets read on demand). I am still not sure 
if all that data should be put into the XMP, too. Or just if it has been 
changed in dt from its original value.

TL;DR: don't expect anything soon. Sorry.

(*) this will most likely be limited to a curated set of fields which should 
however be big enough for almost everyone.
