Adding another option for you - this doesn't have any coloring/limits, just has the update, date made and by whom, stacked. Add this to your views, note the column numbers (if it's at the end of the view and you have fewer columns then it'll work but if you want it mid-view you'll need to adjust column numbers):

column.13.sharecol=true
column.13.textmode=true
column.13.valuefield=lastNote:noteText
column.13.valueformat=HTML

column.14.textmode=true
column.14.value=<br>
column.14.valueformat=HTML
column.14.width=1
