Side Sync Keyboard

[Soapm]

I've been loving this Side Sync feather, it lets me use my tablet from my PC. However, whenever I get to a text field, the internal keyboard on the Galaxy Tab S pops up. Anyway to suppress the internal keyboard?

I was turning on my bluetooth keyboard which makes it think I'm using it but it times out after a while so it would be nice if I can just turn off the internal keyboard whenever I'm connected via Side Sync? Seems it would be suppressed by default...
