@Torstein @matt I used your tool to make chapters for this episode https://borge.forteller.net/@BorgeForteller/episodes/om-varetransport-i-by
and it worked great! I don't think Castopod has support for showing chapters directly on the website, so you need to use a podcatcher to test it yourself.
Thanks a ton! If you want to look into making this a plugin for Audacity, that would be awesome and very helpful. But no pressure ;)
