hi, this is less an issue and more a request, sorry if that means i should put it somewhere else. my datafrog came with some bizarre homebrew that i really want to show my friend but i cant do that while its still in proprietary format. while i know this isnt really the purpose of this project, i just wanted to ask if itd be an easy/feasible thing to provide a utility for doing this or maybe just some insight on how that could be done? thank you!
