Thanks for the module which seems to work on my Samsung Galaxy Tab S 8.4. I enabled on screen navigation as I prefer that over the Samsung buttons but the icons were too wide apart, using this module brings them closer together (especially if search and menu are also enabled). However when in landcape the icons appear over to the left hand side rather than centred, is this deliberate and could they be (optionally?) made to sit centrally? Also, back in the thread you mention adjustable spacing, have you a version with that option working (I like the spacing from the 5 button arrangement but only really need the 3 standard Nexus buttons)?
Thanks again for the work, pleasantly surprised it worked on a Samsung.
