It would be really useful to be able to make board level notes. Not against individual items. At present there is the (i) next to the board Title. But not really designed for ongoing board notes.
For example - You may want to keep a list of key changes to how to use that board. so that staff can be aware of any change of processes etc.
It would be a bonus if you could time and user stamp any notes made and posiible notify anyone included in a new note.
I am not aware that this is an available feature or available via an app etc.
Anyone else find this a usual feature please vote above!
