I decided to use a button instead of using the stock menu button because the latter is placed in the menu bar and I don't want to display it.
Anyway, before I started to think about a complete rework of the home page (yep, I'm thinking about it), I placed some bits of code to take control of the menu bar.
It is, actually, very easy to do...just a json and a sendMessage.
I'll copy here the code asap.
Maybe, it is also possible to let the kindle handle it and have the menu filled with stock options (wifi, store...)!
What I like about WAFs is that I'm lazy and I don't want to port Komic to a kindlet!!
