Filter by Stake on Range Research
Why don't you add this awesome feature?
It's really useful because you can filter by stakes, and that's helpful to check the behaviour of the pool
For example if I play NL25 to NL400, maybe I'm not interested in check how the regular players from NL25 play but as they are in my database their way to play it's going to appear in the range research
You can split a default game type into several game types by stakes in Configuration->Game Types.
