I use Chrome web inspector to inspect all variables.
When I hover my mouse over a variable a yellow popup box appears and I can see what that variable is referencing to.
Sometimes it’s an object that has a lot of keys. Is there a way to make this yellow box larger?

In short,
Find the line where it says:
and replace it with
this will make the minimum size of the popover 500px X 500px
Run chrome with your custome devtools:
chrome.exe –debug-devtools-frontend=C:\src\chrome\devtools_frontend
