An idea about "serve" function.

[UBUKAWA Taro]

For your future consideration, I want to share my idea.
(This is JUST for your information ;D)

I just thought it would be useful if we could have an option to add tile boundaries and collision boxes for styling work when the charites serves the live preview..
Specifically, we could have an option to add the following two lines somewhere in the app.js.

map.showTileBoundaries = true;
map.showCollisionBoxes = true;

If so, we can see the tile boundary and collision boxes during our style editing work.
(It will be optional.)

Thank you for your attention.
I wish I could develop such function by myself...
