Explain the problem as you see it
When working in Tana with nodes that have rich field structure and in particular, have fields with many values the amount of vertical space that is taken up by the field rendering often pushes important data off the screen. Indeed, the area to add new child nodes is below the scroll on many of my structured nodes.
Why is this a problem for you?
I end up having to scroll up and down a lot to see all the information I need while working in Tana and I find myself wondering if I should stop capturing certain multi-valued fields and/or reduce the number of fields I'm using. Both of which seems antithetical to Tana's core approach.
Suggest a solution
If instead I could collapse selected fields in the exact same way that nodes are collapsible, this would solve my problem. If Tana has this capability, then it could also offer a new field configuration option which would be "collapsed by default" much like there is "hide when empty".
