I've tried to look at how menu is populated in browser app and found something useful.

Here is patch for enabling orientation menu item in browser (tested on 5.1.2):

After patching there will be one or two new items in browser menu:

• Lock Rotation / Unlock Rotation
• Portrait Mode / Landscape Mode (it will appear only when rotation is locked by previous menu item!)

Adding of Lock/Unlock Rotation menu item wasn't required in strict sense, but I just wanted to keep original logic.

bapp.setOrientation function (which in fact calls kindle.dev.setOrientation) supports following argument values:

• auto
• portrait
• portraitUp
• portraitDown
• landscape
• landscapeLeft
• landscapeRight

So, browser can be oriented in any way (if someone will write a little bit of additional code).

I'm not providing detailed instruction on how to make needed changes, because it's a bit "dangerous". It will not crash or brick KT, but could stop future firmware updates to proceed. But, I believe, other forum users willl provide user-friendly instructions. Anyway, make backups of changed files before applying of changes!

(Also these new menu items aren't localized. It could be easily done, though: add new strings at /var/local/waf/browser/locales/<locale>/js/strings.js and then use bapp.strings.<your string> in place of menu label value.)

UPD: oh, credits for discovering kindle.dev.setOrientation and all of it's argument values should go to silver18.

UPD2: on boot (i.e. after reboot) all changes made in files of /var/local/waf and it's sub-direcories will be lost, because upstart job /etc/init/appmgrd.conf will uncoditionally copy there files from /opt/var/local/waf. So, it means that (as simple, but not only solution) changes must be applied to file in /opt/var/local/waf too.
