Customizing RV player - Sequence From File

As a world famous image viewer and sequence player Tweaksoftware's RV has to be revealed. There are several option usually have to set.

First of all Sequence From File option which can be set on Preferences / Packages is to allow RV to grab an image sequence from a directory rather than a single frame.

The default option to grab sequence is to drop the folder on RV. If the folder contains more than one image sequence RV paste them on the timeline following each other.
If we use another software to view still images (my personal preference is IrfanView) we have to run RV other way. However we don't want to do it every time from the Desktop or Start Menu. It is much easier to put RV icon on the Total Commander toolbar. In this case drag and drop works fine.
