Hover-over text for task names in LED view

[benfitzpatrick]

The LED view displays task names vertically to conserve horizontal space. To avoid neck ache, we should display the task name as (horizontal) hover-over text when the mouse is over the task name.

Ben, are you thinking of (possibly optionally) replacing the current vertical task names with the hover-over, or having both?

[benfitzpatrick]

I was thinking of keeping the vertical names, but also having the hover-over when task names are toggled off.

It's possible to put something in (that will be switched off for PyGTK versions less than 2.12) like this:

so that we can have hover-over text on the LED icons themselves

We can also have a function to transpose the LED view?
