Geocaching Solver

Since the early days of Locus, the add-on "Locus Solver" https://www.locus-solver.de/ has provided us with a practical way to calculate formulas of Geocaches. This add-on is still working, but hasn't been updated for years and so it's bugs haven't been - and will not get - fixed anymore.

Since Locus 4 already integrated most of Geocaching features, which have been provided by external add-ons in the past, as well:
It would be great and a logical extension to integrate a handy Geocaching Solver feature into Locus main-app too and so don't be depended of an external add-on developer any more.
