Nice. I think there will be a cottage industry of porting every Mac menu bar utility to Claude. I can't use this until it doesn't show seconds. A MM:SS timer is tolerable when it's in my menu bar, but a ticking timer right where my focus is during a work session would be very distracting to me.
The best version of this, for me, would be one that leans into Claude's ability to customize its own statusbar. If Claudoro is in charge of writing timer data to somewhere Claude can see it, I can tell Claude exactly how to display the timer in the statusline.
