You can set the display option for a field to have a vertical scroll bar - also only visible when scrolling.
This is great, but it works only if the field is able to edit.
There are cases - especial on FileMaker Go solutions - where text content is much more than the visible are of the field.
This extra content is hidden, and sometimes it is not practicable to use a webviewer or popover to view more lines.
I think having a (working( scroll bar here the user experience could be much better and foot print of layout objects would be much smaller.
