Do not install with Cobblemon Pokenav 1.3.0+
As of version 1.3.0 integration is built into the mod and can be enabled in the config. I haven't checked what will happen if you put them together, but it's quite possible that nothing good will happen.
The mod adds a new feature to the pokenav from the Cobblemon Pokenav mod, which allows you to see the current streak level from Cobblemon Counter, which may be useful if you also use Cobblemon Unchained or similar. In addition, similar to how Unchained increases the chances of spawning Pokemon with any features, such as hidden abilities, depending on the level of the streak, the mod gives some chance of spawning Pokemon with an egg move. The chances of an egg move and the number of captures required to raise the level of the streak can be adjusted in the config
