I recognise the fact I am minority (Locus users having Samsung Galaxy Note 1,2,3). But it's stilus, s-pen, is very precise instrument and simply pleasant to use. I'm sure, menion will understand me

So I'll just leave this topic here, waiting and hoping.
Suggested functions for S-Pen:
1. Precise selection. Especially when drawing a route.
2. Highlight point name when hovering over it, not touching
3. My dream - highlight wikimapia polygon with name - the same way as their mobile site does, when browsing it with Chrome.
4. Drawing a route just freehand, not clicking points.
That's what is on my mind right now. Maybe other users can add something else.
