Did you ever end up experimenting with this @antoniokov?
To me, this feature (alongside grouping in lists/tables by any field and self-relations-on-bottom-levels are hugely impactful usability features that your primary competition already have and would likely contribute to higher adoption/lower churn if they were addressed.
I know the other 2 features I mentioned are in the calendar for Q1 2024 so hopefully drag & drop improvements could be prioritized soon after.
