Sorry, but I am not too sure if these suggestions were already made, but here they are, and I feel that they would increase the efficiency of gathering materials, and moving materials around a lot faster.
1. Create a Cart that you are able to build out of either scrap metals, or woods. With this cart you can carry a massive amount of materials, and still be able to move it around without getting tired as quick, unless there is too much material causing it to be too heavy. ( This idea was in Wurm Online ) This will really help the production rate of tribes and just moving materials would be a lot more efficient.
2. Create a system where storing materials such as bricks, sand etc. Is a lot more organized. Or even storing personal belongings within a tribe area is more organized. Maybe a system where it allows you to name the bin, so if you hover your mouse over it, it says the name of it as if it were the same as a player.
3. Create a friends list , tribe list where it shows who is online. Im sorry if this is already implemented, but I still havent found a feature that shows if a player is online or not. I asked around, and no one knows about it either. Implementing this would be really helpful. Instead of asking in tribe chat who is on, you can just manually see.
Sorry again, if these suggestions were posted before again. I just really wanted to put this out!
