Hello, everybody. I have a suggestion about the thumbnails that are added to the TOC of QGIS. Suppose that I load a GDAL Virtual Raster Catalog (.vrt file) that contains 2000 raster files or even more. In this case, when I load the .vrt in QGIS (even if I have configured a good scale dependent visibility) it takes some minutes to load. I suppose that the problem is that QGIS is generating the thumbnail to show in the TOC (it has to generate the thumbnail from 2000 raster files). It could be a good idea to add a QGIS preference to allow the user to decide if he wants to generate/show or not the thumbnail of every loaded layer. Thanks in advance. Santiago Lastra.
