@ThomasGranheim Is #339 related to this? Does it need a separate PR, or can it just be added to this? Also, can you resolve the conflicts <3

Fix conflicts (update from dev), and update CHANGELOG (same change as in separate PR)

[ThomasGranheim]

Does it look OK now? Fetched from the dev branch and merged it into new feature branch. Also added the CHANGELOG commit to this PR.
