Rearrange, resize or disable bottom-right Change Keyboard button (or any button) - disability

[JeffKang]

#Hi.
I have a really bad repetitive strain injury, and Hacker's Keyboard has thankfully allowed me to use the computer more.

I do a fist pronation, (thumb facing up, and then inwards) and I tape the edge keyboard buttons with my pinky.

I use AutoHotkey to remap the edge buttons to do different things.

I've been using an old Nexus 10, and I just tried a Lenovo Tab 2.

With the Lenovo, a new Change Keyboard button is in the bottom right, and I keep accidentally hitting it when I mean to press the right arrow key.

I don't know if the Change Keyboard button addition has to do with a newer Android or Hacker's Keyboard version.

Maybe this comment has to do with the issue 13 custom layout request:

Support customizable key layouts? #13
#13

New feature: Hiding buttons #517
#517

The DEL key should be in the main keyboard, sugestion: replace the right shift key or «» key. #148
I'll resume work on customizable keymaps (see issue 13) once
I've wrapped up the current pending Market release. sahityakumarsuman/hackerskeyboard#148

Enhancement request: split layout (aka "thumbs layout") #423
I would like this as well, my hands hurt from using a 10" tablet and hackers
keyboard
#423

Customizable emoticon list #210
way to edit the list of available emoticons,
just like the suggested punctuation can be edited.
#210
Sorry, I'll need to defer that until I have more generic remapping support in
place, please see issue 13 for that.

I'm not looking for new actions or keys (AutoHotkey remapping can take of that).
I'm looking to relocate and resize existing keys.

Thanks so much for the program.

Edit: I think the Change Keyboard button is part of the Lollipop navigation bar.
The request to resize and rearrange the other keys is still there though.
