Can you  make the Background colour box larger.  (maybe add space brfore & after text)

The "A" and the "t" are spilling outside the colour box, when the user pulls up the quest menu.

Also maybe add a % completion option to the bottom of the quest

Not sure what u mean.
Can u please provide a screenshot?

as u can see i dont have this problem with newest version and default config.
Whats your screen resolution?

sorry checked other server ,they also have it.

   [Info("Quests", "Gonzi", "2.3.5")]
    [Description("Creates quests for players to go on to earn rewards, complete with a GUI menu")]
    public class Quests : RustPlugin
    {​

thats the plugin code....

THIS IS your Button code....

 {
                buttonColor = QUI.Color(configData.Colors.Button_Accept.Color, configData.Colors.Button_Accept.Alpha);
                buttonText = LA("Accept Quest", player.UserIDString);
                buttonCommand = $"QUI_AcceptQuest {entry.QuestName}";
            }

THIS is your translation config....

   { "Pending", "Pending" },
            { "Completed", "Completed" },
            { "Accept Quest", "Accept Quest" },
            { "Status:", "Status:" },

fixed with next version for cancel and accept
