With the Nintendo Switch firmware update 10.0.0, which is available now, you can transfer your downloaded games directly from the system memory to an SD card or vice versa to free up space. With the update, you can also reassign buttons on your controller and visualize your user profile from a new collection of new Animal Crossing: New Horizons icons.
The direct transfer of data between the internal and external memory of the console is a function that has been in demand for some time. If you were previously full of internal storage and wanted to move games and updates to an SD card, your only option was to download them again. This new feature should make it much faster and more convenient. According to the patch notes, "downloadable software, update data, and DLC" are supported, but save data and "some" update data cannot be transferred to an SD card.
The new firmware provides support for button remapping. Here I swapped the two shoulder buttons on the left Joy-Con.

The new function for reassigning buttons can be accessed via the section "Controllers and Sensors" in the system settings of the console. It works with the integrated controls Joy-Cons, Pro Controller and Switch Lite and allows you to change your buttons and analog sticks. Once you have set up a new configuration, you can save it as one of up to five presets. This is useful if you want different button layouts for different games.
Switch software version 10.0.0 is available now. You can update your system manually in the "System" section of the Settings menu. However, I found that my console was updated automatically when I started it this morning.
