I don’t remember if this was a request, but for my part, after using the « Room devices » box as well as the « Chart » box, I found it annoying to still have in the features list all those already selected.
So, similar to the devices selection field in the chart boxes, I added a filter in the selection field of the « Devices » box to remove from the list all devices already selected.
