Very well done Edvard

I've only managed a quick look so for:
+ Stop / Start works well.
When I make a second task:
+ the task that is active remains highlighted, no matter which task has focus -- I think that's good (but see below)
+ when I double-click [The Time] it (1) gets copied to clipboard & (2) stops/starts (as appropriate) - that is very nice

+ are you using Corbel for the timer? If not, it's something similar - makes very good legibility :up
=>
- The font size (for time) is too big here, and is cropped at the bottom (my monitor resolution is 90ppi - probably below average these days)
Changing tasks seems to be problematic:
- I get confused about which task has focus:
I currently have two tasks: when one is selected, the timer is still related to the other ( I listed this as a +ve above :-/ ) =>
- even when I stop the timer on the active task, I cant find how to change to the other task.
I wonder if we need a stop/start button here?
Will have a longer test tomorrow
