For people that have trouble with the QList expansion, please update the current QList part in qt5.natvis with:

   <Type Name="QList<*>">
       <AlternativeType Name="QStringList"></AlternativeType>
       <AlternativeType Name="QQueue<*>"></AlternativeType>
       <DisplayString>{{ size = {d->end - d->begin} }}</DisplayString>
       <Expand>
           <Item Name="[referenced]">d->ref.atomic._q_value</Item>
           <IndexListItems Condition="QTypeInfo<$T1>::isLarge || QTypeInfo<$T1>::isStatic">
               <Size>d->end - d->begin</Size>
               <ValueNode>*reinterpret_cast<$T1*>(reinterpret_cast<Node*>(d->array + d->begin + $i)->v)</ValueNode>
           </IndexListItems>
           <IndexListItems Condition="!(QTypeInfo<$T1>::isLarge || QTypeInfo<$T1>::isStatic)">
               <Size>d->end - d->begin</Size>
           	<ValueNode>*reinterpret_cast<$T1*>(d->array + d->begin + $i)</ValueNode>
           </IndexListItems>
       </Expand>
   </Type>

This fixes some Node* expansion issues when you have a struct that is exactly sizeof(void*) (which somehow end up being in a Node instead of being directly in the QList)

Someone might want to apply this as a patch to the next version of the qt5.natvis file.

QDate showing MDY in addition to Julian day

It would be an improvement for qt5.natvis if QDate was shown not only as Julian day

  { julian day = 2459412 }

but also in a DMY form like this

   { julian day = 2459412 }
      [day]: 16
      [month]: 7
      [year]: 2021
   [Raw View]: {jd=2459412 }

this can be done by using

 <Type Name="QDate">
   <DisplayString>{{ julian day = {jd} }}</DisplayString>
   <Expand>
     <Item Name="[day]">((5 * (((4 * (jd + 1401 + (((4 * jd + 274277) / 146097) * 3) / 4 - 38) + 3) % 1461) / 4) + 2) % 153) / 5 + 1</Item>
     <Item Name="[month]">((5 * (((4 * (jd + 1401 + (((4 * jd + 274277) / 146097) * 3) / 4 - 38) + 3) % 1461) / 4) + 2) / 153 + 2) % 12 + 1</Item>
     <Item Name="[year]">((4 * (jd + 1401 + (((4 * jd + 274277) / 146097) * 3) / 4 - 38) + 3) / 1461) - 4716 + (14 - (((5 * (((4 * (jd + 1401 + (((4 * jd + 274277) / 146097) * 3) / 4 - 38) + 3) % 1461) / 4) + 2) / 153 + 2) % 12 + 1)) / 12</Item>
   </Expand>
 </Type>

instead of

  <Type Name="QDate">
    <DisplayString>{{ julian day = {jd} }}</DisplayString>
    <Expand></Expand>
  </Type>

as it is done currently.
