As reported here : Notifications Pane: Fields with different grid caption not being read from Forms >Current Grid [& other problems] and there : Notifications pane -- what is it?

 

the Notifications pane only shows info for

1- Columns (fields) headers

2- fields names in the properties pane

3- incompletely displayed cells content in the grids (if the cell shows all info, notification shows nothing -- at least, that's what I'm observing here).

4- text cells with carriage returns inside (shift-enter, actually)

 
2 possible enhancements :
 
1- IMO the notifications pane  should show cell details and field details all the time on "mouse over", whether the field content is displayed completely or not, or has carriage returns or not.

2- the grid info tooltips should also appear in the notification pane area  (and , why not, any other tooltip?)
