Could we use string compression as a quick localStorage improvement until we have IndexedDB/WebSQL support?

I just stumbled over and was wondering if we could use it as a quick drop-in improvement for handling more data in localStorage, until IndexedDB support is ready.

May be an option. The only downside I see now (apart from performance, which I haven’t tried) is that it becomes harder to inspect the current state through localStorage, see

The real gains would be achieved by compressing content values, so we could just leave everything else uncompressed, and at least gain a little more capacity, right?
