This is based on #68, expecting it to get merged first

TODO:

• [x] #68 is closed. Need to rebase.

#69

Nice

makes sense, thanks! but this PR cannot be merged as based on #68 and #68 is not that clear, at least not to me :)

however, this PR can also easily be redone standalone, maybe after #70 is merged (to avoid conflicts)
