About
Starts counting as soon as the action is on you and displays the elapsed time on the table.
Screenshot
How to use
Select 'Settings' from the tray menu to change the font and add 'ranges' (the text color and background color of the timer box can change based on the amount of time elapsed). To adjust the position of the timer box, open a table and move the box to the desired position (drag&drop) while the table has the default size.
Limitations
NOTE: The limitations do not apply to No Limit tables, as the script can detect whether a table is active by looking for the slider control.
Will not work with overlap
Will only work with the hyper-simple theme and the No Images theme (although could be edited to work with other themes).
