The best way to ensure that a product matures and grows into something amazing is to have an awesome userbase who provide great lengthy feedback
I'm currently adding 2 features - a big one and a small one:
- The ability to change the world time
- An inventory editor
Could you possibly expand on your point that said:
On the players tabs (whiltelist, banned, etc), add a "connected" tab and display connected players there instead of in the treeview. For large servers with many players, the treeview is not the best place to show connected players (IMHO).
How would you display them? Just a list? Or some kind of grid view that has some vital statistics about each player?
