nano kontrol experience and improvement

[antokhio]

Hello, i'm professional vj, you can check my works vimeo.com/antokhio

I always use nano series because it's handy to have in the bag
but first of all why the knob's aren't glued is the glue cost's too much? Second day i bought a controller i already don't have one knob, and where should i get a replacement???

Second in music production slider goes from zero to one and as vj i almost ever use it from minus one till one. So is it hard to add small tick when slider or knob crosses 0.5, because now i have to look in to interface whatever i try to put something on 0 (right in the middle) it's so annoying! You buy controllers not to look on the interface after!

Small tick when you hit 0.5 would do the perfect job!
PLEASE!!!!
