i want to create a custom time tracker, with a start/stop button on board, card and checklist level.
time can only be tracked with 1 button at the time, starting one button should stop the previous one. (I could also do that on my side via API, then i just need to be able to change the state of the button.)
How do I get my powerup to add a button to checklist items?
And any other tips to get this started and finished quickly are extremely appreciated.
