Choose a friend with matching pools
🚀 Feature Proposal
As a user, after selecting a pool I want to start a duel with, I have the possibility to choose one friend from a list of all my friends which have matching pools (with the one I've choosen). After clicking one of them, a new challenge request is send to the selected friend. THe friend will receive a push notification (if he/she enabled this feature). The user will be redirected to his/her updated duellist screen.
Motivation
By this design a user can first select which pool he/she wants to play and then automatically sees which friends have matching pools.
Technical Details
Requires #32

Player "Banana123" chooses pool "Math 1". Now the player sees his/her friendlist filtered by those friends which have matching pool. "Banana123" clicks on his/her friend "Tomato789". "Tomato789" has push notifications enabled and now receives one. "Banana123" gets redirected his/her duellist, now seeing the freshly srtarted duel with "Tomato123" right on top of the list.
