VTM is an open source library.
Some users may have their own separate Mapsforge / VTM
implement features and not contribute them back to the
(there are examples in issues list)
And it has happened in the past with Mapsforge,
resulting in the fragmentation of the community.
Other users are more generous and contribute useful features.
e.g. a recent pull
Instead of complaining to maintainers to implement something their
they can study the code and contribute, after discussing it
here in the forum
And not make the repository a museum of requests,
which wait for someone else to implement them ...
Our top priority is maintain the existing code and shaders
for compatibility / performance for current users and apps.
You can create new clean shaders and extend existing classes
to implement new rules in themes, etc.
