It would be nice if the Dock Icon changed somehow when Pause Breaks was selected; for instance, change the color to orange or red, or put a red slash through the logo, or even superimpose the 'pause' symbol over the icon. Something to remind me to turn it back on, basically.
Also, could you add "pause/resume breaks" to the context menu from the Dock Icon?
(I'd love to see these tweaks in a non-Leopard requiring version; I don't upgrade for a few iterations, say 10.5.3 or so).
Re: "Pause Breaks" visual
The good news is that I do plan on adding those features in Time Out 2.
The bad news is that Time Out 2 will require Leopard.
I may consider adding some variation of those features in an earlier release, but no promises.
