INFO::
The tool is quite simple: rather then having to depend on outside sources for firmware NCA's you can now dump them yourself in a targeted efficient manner directly on your switch.. I wanted to cut out the middle man. A means to a end, a tool designed specifically for firmware dumps.
No longer are you forced to dump your entire nand to get your hands on the latest firmware, this was a huge waste of time.. or have to patiently wait for the files to become available online, which again is another waste of time - expect delays!
What you do with the files is entirely up to you, development purposes? downgrade snapshots? latest firmware upgrade? Analysis?
Dumping process does take a while, but much less time than a full NAND backup that's for sure! Once the dump is complete, simply open ChoiDuJourNX and target the dumped firmware directory to install.. simple, easy & efficient.
DOWNLOAD::

PENDING UPDATES::
You'll get the following notification when a new firmware has been downloaded and is ready for installation:

If you don't have the "system update ready" notification in settings, you can force your switch to download the latest firmware update by entering the "system update" menu.
DO NOT PRESS THE LARGE "UPDATE" BUTTON AS THIS WILL PROCEED TO INSTALL.

A pending update dump will also dump your current firmware, there is no need to dump both. The switch appears to update only what is necessary, recycling older firmware files where possible to minimize firmware update size.
When selecting a pending update dump folder (two firmware versions in the dump folder name) in ChoiDujourNX you will be presented with an option to install either your current or the pending update firmware.
