What is that cryptic text on the 4.3 release? Those are openers ids.

First time you discover a new opener it become yours, you can view and see your found openers on this page.

If you name the opener it will show up ingame as that name.

The openers have the following syntax:
h = hold
r = relax
f = foward
b = back
- = no grip
+ = grip

The stats for the openers are global, so if you someone uses your opener it adds to the stats.
