Hi Solar, I've been messing around with the free version of MasterPlan and just bought the full version today. There are a lot of good features and I'm looking forward to moving over a lot of project notes from OneNote.
I have a suggestion regarding the timer trigger behaviour. Regarding the three modes toggle/set/clear, the behaviour of the toggle trigger maxing out the "numbered" card (e.g. 0/100 -> 100/100) seems to be the same as the "Set" trigger, albeit toggle also allows it to jump back down to 0/100 as well.
I feel the "Set" trigger would intuitively be better as an +1 counter for this, allowing the Numbered card counter to increment by 1 for each set time elapsed. The use-case for this would be setting a goal of "Complete 30 minutes of 'Task A' 10 Times", setting the timer to 30 minutes and attaching a Numbered card to 0 of 10.
Keep up the great work!
