Hi
“General” room has been updated to include all nodes that exist in a space. It now works as a centralised node management directory, which was missing previously. That’s why removal of nodes from General is not allowed. Basically it holds all the nodes in your space.
However, we understand that this has created a room with long lists of unused nodes. Hence, we are already working on the ability to delete nodes, so that they no longer appear across the account.
This should be available very soon, likely by end of this month
