Explain the problem as you see it
Node descriptions, especially when used in fields, decrease the mandatory info density on the screen with no workaround.
Why is this a problem for you?
I don't want the descriptions making every page longer, because I like having an info dense workspace.
Suggest a solution
Allow the option to show node descriptions when you hover over the node's icon. There is already info here, so there shouldn't be very much to change. Although obviously I don't know how Tana works under the hood that well.
