Taken from the 2nd feature request of this other post : http://bexplorer.codeplex.com/discussions/352751#editor
I thought it deserved to have its own issue.
The "Select" group (in the Home tab) now contains the Conditional selection. It's really useful but not fast enough if you want to select all files of the same type than the one you have already selected.
Frankly, it would be really useful to have another icon/button (maybe called "Select same type files") that would select all the other JPEG files if the currently selected file is also a .jpg file.
