Thanks again for a great program!
is there such a function - specify for which file types to create preview in "extra large thumbnails" mode?
for example - I would like to create previews only for JPG and PNG files.
and second as a:
suggestion - you show 1-folder front 2-folder back +and only 2 previews - it is few here picture

i show side by side how show your program preview and other program - same folder, in both cases we see that "this is a folder" but in second case - amount of data which we can se from folder is much more...in Everything we can, if it is not possible to show such large folders, you can show them to the small icon - then it is important to show more ELEMENTS from them
