Hi Robert,

A big thank you from me as well!

My takeaway from this is that I should put more effort into refactoring and 
modernizing the codebase in general. I already broke a large number of 
dependencies between different parts of KPA - modularizing the core components 
(database, thumbnail storage, exif database) and adding unit-tests is not that 
much effort from here (at least it seems far more doable than a year ago).

With the database code as an isolated component and with a decent test 
coverage we can start going after the not so low hanging fruit (like a cache 
for the database file).

Cheers,
  Johannes
