Nice!, also, I was playing a bit:
- With the --map flag in coffee compiler I can use debbug function in
browser
- With a lib source-map-support.browser.js I can use error backtrace
function in browser

These points work in my chrome, but when using "enable sourcemap" on
osbuild did not work any of the above points.
What browser are using to web activities?

not work.
