Personally, the main thing I want to see is expose simpler and lower level
APIs.  For my uses (backend to git server), the leveldb API is plenty
powerful.  Most of the time I'm using IndexedDB, I'm getting frustrated
because it's way more complex than I need and gets in the way and slows
things down.

Would it make sense to standardize on a simpler set of APIs similar to what
levelDB offers and expose that in addition to what indexedDB currently
exposes?  Or would this make sense as a new API apart from IDB?

As a JS developer, I'd much rather see fast, simple, yet powerful
primitives over application-level databases with indexes and transactions
baked in.  Chrome implements IDB on top of LevelDB, so it has just enough
primitives to make more complex systems.

But for applications like mine that use immutable storage and hashes for
all lookups don't need or want the advanced features added on top.  IDB is
a serious performance bottleneck in my apps and when using LevelDB in
node.js, my same logic runs a *lot* faster and using a lot less code.
