Currently, barters are not sorted in any specific order. This makes navigating the barter information window tedious, even with a searchbar. I suggest adding sort options that allow barters to be sorted according to their 1) chains; 2) grade; 3) type (e.g. Seacoin, Upgrade Materials) and 4) distance. As follows are some examples:

1) Barters sorted according to chains:

Barter chain 1: A -> B -> C -> D -> E

Barter chain 2: V -> W -> X -> Y -> Z

2) Barters sorted according to grade:

Barter chain 1: A -> B -> C -> D -> E

Barter chain 2: C -> 100 Rock Salt Ingot (example of an upgrade material)

Barter chain 3: E -> 500 Seacoins

3) Barters sorted according to type:

Barter chain 1: A -> B -> C -> D -> E

Barter chain 2: C -> 100 Rock Salt Ingot (example of an upgrade material)

Barter chain 3: E -> 500 Seacoins

Barter chain 4: B -> X

Barter chain 5: 500 Nutmeg -> 300 Acacia Sap 

4) Barters sorted according to distance:

Barter chain 1: A (Eberdeen) -> B (Pilava) -> C (Lema) -> D (Halmad) -> E (Hakoven)

(Sorting UI could be similar to those used in the Central Market or Quests)

(Proposed location if a sorting arrow is used)

I strongly agree to these suggestion especially the distance option. I personally chose my barter route based on distance because of that i have keep dragging maps left and right for a while before i'm able to make decision.

Wow~ thanks for the information. Actually barter worst situation is attacked by those pk player. They destroy ur ship n dun get any panelty even u able to fight back n destroy their ship. So unfair.. n ship battle normally who attack 1st who win...

Hmm.. that's true @LucyMisora. I am not sure if they lose karma in the process, but ship PvP definitely discourages players from bartering (e.g. barter goods lost, sailors sick). I think normal karma rules should be implemented in sea PVP, and maybe Outlaw content (e.g. Muiquun) can be added for negative karma sea players.
