We are using context field to make it easier for trasnlator to make translations. Best is to give them screenshot with english text so they can see how it is used and where. So our context-term unique keys are not working anway and we don't care much about duplicates. we can handle this in other way. What we are missing is POEditor not showing links in context as clickable links which makes it very difficult to open link.
As Brian suggested we are now using commnets for this. But this is somewhat hidden. Other solution could be to improve its rpesentation and 1. add text field to ADD term window below context firled to add comment straight away when adding term. and in translation wondow to show first comment automatically below term in list wihout need to open comments window.
