very helpful Rated 5 out of 5 stars
I have found it to be very useful for my add-on development(proxilla). As any developer knows, you have to keep reloading the chrome constantly after making changes to your code to see the updates.
On a side note, as I was debugging my add-on, I noticed a warning for yours referencing the style of your statusbarpanel. Statusbarpanel-iconic is a class, not a style. Defining this correctly will allow you to use stylesheets to assign an image rather than using an image url.
Keep up the good work.
