Thanks @FJP
For the drag and drop function I am using the Draggable elements plugin and then I applied what I learned from reading everything I could find on the forum, including this and this). My kanban style board is still buggy and I will be spending more time on making it solid though.
As for your question around voice recording, that is a misleading UI issue (thanks for helping me see that). Teeming does not record audio, instead it assigns a random order to speakers and starts a timer when you press play, so that speakers can see now much time they have been speaking,
There are a couple of audio recorder plugins for Bubble though, this free one from Bubble and this paid from Zero Code.
