Create a log file only when needed instead of on initialization?

[osa1]

Currently when using a file target flexi_logger creates the log file on initialization. My app doesn't print a lot of logs by default so that means an empty file is created for every run. Would it be possible to at least add an option to create the file only when needed? (i.e. the first time a log line is printed)

Makes sense to me! I'll pick this up on the weekend (hopefully...)
