Good initiative towards a very very simple but extremely useful idea. Thanku Didier.
But I wud like to add some suggestions:
1) Plz Make it more customizable both towards refresh period and towards choice of symbols.
2) To add more of GUI enhancements U can allow user to choose the display color since RED color seems too difficult on eyes + Instead of displaying the text in the status bar can u give an option to only display the symbol , since text gets too large and occupies lot of space in status bar.
I did update ur extension files myself to suit my needs but it wud be really really useful if u cud consider adding some more customizations.
...and thanks for the kind and useful review...
