* Stabilize and optimize the ServiceWorker mode, to try to make it the default mode (on platforms that support it). This mode should be much more sustainable in the long term.
* Improve performance by using WebAssembly (on platforms that support it) for the bzip2 decompression. Preliminary tests let us hope around 30% performance improvement.
* Investigate on compiling the libzim to WebAssembly. If it's technically possible, it would allow to benefit from all the features and optimizations of this library, without the need of re-implementing them.
