How can I rename the column headers on the Team page - ‘locaine drinker’ means nothing to me.
These column headers texts cannot be changed within the UI.
If you are using a self-hosted version of Taiga, you could modify the code here.
In case you wonder what the iocaine is, you can read more here: What is this Iocaine thing in Taiga and how should I use it?
Many thanks for that.
