It works quite nicely now, I did small changes to code:

Now there are two client tags **DisableOverlays** boolean and **OverlayDisabledUntilTS** DateTime

**DisableOverlays has Expression:**

```auto
try(
   now() < {[Client]OverlayDisabledUntilTS}
,0)

```

**Tag Event Value Changed:**  
`system.tag.setOverlaysEnabled(not bool(currentValue.value))`

**And when I load any window, I use code:**  
`system.tag.write('[Client]OverlayDisabledUntilTS', system.date.addMillis(system.date.now(), 1500))`

This adds the support of changing the estimated load time of each window, based on their complexity. To make it bit nicer, I would also wrap the tag write call to some project library, so the complexity is hidden in normal use.

Thanks @pturmel and @Paullys50!
