Visualisation of cached area

[xxc]

Hi,
Is there a way to view the area of cached tiles ? I mean a big map with (in red) the region cached in the sqlite file for a specified zoom level ?
External app ?
Thanks

yes, this should be really really nice ... but actually this is not possible in Locus. I think this is really CPU power intensive task and much better should be some desktop tool for all these stuff with maps ...
