@ade, Some feedback: (1) while the portrait layout indeed looks good, in landscape mode a few pixels at the bottom of each of the three timers are cut.
(2) if I add a new timer and hit SAVE and then go to the "choose dish" button I only see the previously saved items, but not the new one. Using the "Save config" option does not make it appear either. I have to close the program and start it again.
(3) I start a timer and then stop it manually. The remaining time is still visible. I then click on the "Time (hh:mi)" button but then cancel it (click outside the window). The remaining time is not there anymore, but the original time. OK (3) is not really a bug or anything, but somewhat inconsistent behaviour.
Regarding (1), I'm using the HydroCarbon theme. Not sure if the font sizes on cooktimer are hard-coded or if there are affected by the theme (I'll try switching to a built-in theme and see what happens).
How much CPU does it consume? My experience from other countdown-timers is that thay consume alot CPU counting seconds as I understand.
