I'm not sure what you mean by 'default input device'. As you set up PIE you can customize the number of tiles (up to 5) and have up to 2 levels of tiles, for a total of 10 possible shortcuts. The first level is set by default to be Android navigation buttons (soft buttons), 'back', 'home', 'menu', 'search', 'multitasking'.
If these defaults have gone missing, or there are less than 5, PIE will reduce the number of 'buttons' that show up when activated, i.e. graphic UI will be adjusted
I could reduce each level of PIE down to 1 'button' if I choose.
Now that I'm thinking in this context, I'm guessing that is what you mean by "default input devices". If I am reading you right, you can set up to 5 and there will be no issue for the Note 3, likewise say that you only wanted three 'buttons' or 'input devices" (Home, Back, Menu) that wouldn't be a problem either. PIE will adjust the Graphic UI to match your settings, there won't be 5 'buttons' on screen if you only set 3 of them. I hope I'm being clear?
Honestly I don't blacklist any apps from from PIE
Can I ask why you want to Blacklist an application? Once I set the apps I want in my PIE I don't worry about the other apps I have installed on my device. I set those to be my most used apps, for the particular device om setting up. For instance, my Note 3 2nd level PIE app shortcuts are these
I have them set, and if I need to change them I just sift through the apps and replace them (I agree it does take some time to load, but once you have it set as you launch PIE it is seamless). I guess I don't understand why you want to Blacklist an application, when you only need to set the ones you want to have appear on the PIE launcher. Not that you need to validate your reasons to me, unfortunately I don't use this feature myself so I don't think I can be very helpful about this. Hopefully someone else might be able to lend some advice.
Let me know if I was on target about your question on setting the 'buttons' up.
