Persist breakpoints across sessions, per-app

will this be implemented?

I would like to see this as well. It's really difficult to sometimes debug my application properly since certain code only runs when state is rebuilt.

Is there PR opened for this?

Adding debugger() statements to my code is possible. But having breakpoints not disappear when using devtools / IDE would be great, at least in a situation when the source file does not change.

Would be really nice if this feature would be added.
Its especially hard to debug stuff like singletons etc. when breakpoints are wiped everytime I do a hot restart.
