On Kronos server they have some chat filter that not allows you to send colored text in chat. With the latest version of questie I cannot link quest names in chat with Shift + Click no more.

Please add configuration to be able to switch to old version of quest linking

pseudocode

if (useNewLink) then
    ChatFrameEditBox:Insert("|cffffff00|Hquest:0:0:0:0|h["..gsub(this:GetText(), ".*%] (.*)", "%1").."]|h|r");
else 
    ChatFrameEditBox:Insert(this:GetText());
end
