Hi, thanks for submitting. Could you limit the features to those in this guide?

The features list is used to automatically generate search options. Spelling is important so we don't end up with a list that is out of control (it has happened before) by having lots of variations. You can always put anything cool that isn't on the features list down in the description.

Hi, could you limit the features to those in this guide?
https://learn.adafruit.com/how-to-add-a-new-board-to-the-circuitpython-org-website/adding-to-downloads? The list should only be limited to these 10 items and spelled exactly the same:

• Speaker
• Solder-Free Alligator Clip
• Feather-Compatible
• Battery Charging
• Display
• Wi-Fi
• Bluetooth/BTLE
• Robotics
• LoRa/Radio
• GPS

So for instance BlueTooth 5 (nRF52840) should be changed to Bluetooth/BTLE and things like DC-DC and Optical sensor aren't even on that list. Thanks. This helps keep our feature search to a reasonable length.
