@ntnsndr one user reported it broke their workflow, said it was too wide and it made the UI uncomfortable to read; they declined providing more details for now so I'm unsure how to work around their issue. Therefore I disabled it altogether.
Unfortunately https://social.coop/@flancian/112956289256023898 is also a thing apparently.
So maybe it'll also be single-column for me. Or I'll fiddle with userscripts :) But most people won't, so they will miss out, which is a shame.
