Hi @pireddag, thank you for the swift answer. I just re-checked supports-slidemove? in scheme and it works!
Is there a nicer way to reorganize slides?
Ok, that is nice. I did not look into the code and I do not know what happens, the author, @jeroen, might know more. Please let me know if you find the buttons and can use the plugin.

Yes, everything works well, thanks!
