Can someone tell me if and how can I display some info about selection in the viewport?
I use this a lot in Soft, especially when modeling - I often peek at the number of points/edges/polys I have selected when working on dense meshes since sometimes you can't tell for sure if you selected one component or two (that are occupying the same space).
Apart from that it offers other useful info.

In the Display Options, Guides tab, there is a Geometry information option that can be set to Selection Only (only display #selected) or Always (display prims, points, selected).

Nice. Thanx.
“non-commercial edition” is getting in my way of achieving greatness though

That issue has been fixed, in the first daily build of 15.

Awesome.
