Distinguish between the most recently ticked nodes and previously ticked nodes at some point. #50
Description
Is your feature request related to a problem? Please describe.
I want to see the difference of ticked node between the node has ticked and the node just was ticked.
Right now, I can't tell whether a node is just ticked(the most recent tick from root node) or it has been ticked from some point before.
Describe the solution you'd like
Refresh button to refresh all the green, orange, red node to see what nodes are traversed from the upcoming tick.
Describe alternatives you've considered
Maybe draw different boundary for the ticked node. If a node has been ticked but not for the most recent, draw boundary with dash-line just right now.
For the node that was just ticked, draw boundary with bold line.
