Thank you very much for this feedback, it is super useful. Do not hesitate to post this type of comment to geogram's github (https://github.com/BrunoLevy/geogram/issues https://github.com/BrunoLevy/geogram/issues) Please note that the Logger mechanism can be redirected to a GUI, it is used for instance in the GUI applications made with Geogram (https://github.com/BrunoLevy/geogram/wiki/Applications https://github.com/BrunoLevy/geogram/wiki/Applications) and in Graphite (https://github.com/BrunoLevy/GraphiteThree https://github.com/BrunoLevy/GraphiteThree) About using std::string as path under Windows, I understand that it may cause some problems with users who use general characters in their directories, but it does not prevent the application from running and from loading/writing files. In the future, when std::filesystem is well standardized, I plan to get read of my FileSystem implementation.
