When you create new module, you always got problems with OTUI design. Why X element is on that position? What am I clicking?

I can’t solve all these problems, but my module can help you debug your UI without milion prints to console.

With this module you can easily view tree of elements on given position (under mouse cursor):

It also works before login:

modules/client_ui_debug/client_ui_debug.otmod

            ) then
                smallestWidget = widget

    if smallestWidget then
        clientUiDebugHighlightWidget:setPosition(smallestWidget:getPosition())
        clientUiDebugHighlightWidget:setSize(smallestWidget:getSize())

    local widgetNames = {}
    for wi = #widgets, 1, -1 do
        local widget = widgets[wi]
        if (widget:getId() ~= 'highlightWidget') then
            table.insert(widgetNames, widget:getClassName() .. '#' .. widget:getId())
