I've compiled a firmware with STORAGE enabled, but putting more and more pages on the ESP8266 it seems like there's not even 1 MB of free storage available while flash is almost 2 MB:
```
/*
>require("Storage").getFree();
=196608
>require("ESP8266").getFreeFlash()
=[
  { addr: 2097152, length: 1048576 },
  { addr: 3145728, length: 262144 },
  { addr: 3407872, length: 262144 },
  { addr: 3670016, length: 262144 },
  { addr: 3932160, length: 241664 }
 ]
*/

```
Somehow I expected the STORAGE module to use all available flash storage, not just the block where the program and wifi data is stored. Is it the intended behavior, or a bug in my build?

Just a hunch: ESP8266's flash is divided to multiple parts: Running code, SPIFS, OTA partition, etc. My guess is that's why you only see that much free flash.
There are compiler flags to set flash partition on the ESP8266, and I think separate compiler options to reserve space for Espruino's storage.
