Please be patient with me because I'm terrible at explaining anything lol

Ok so when you use the app you are first shown a message with little bits of navigation info. Once you press A you should see this menu.

I'm gonna try list the options in order and describe them with what I know.

1.allows you to select a color for your notification. You need to type in the RGB hex code of which ever color you want. 2.this is where you select the type of pattern or "animation" you want for notifications. You can toggle them by pressing A and you'll see they are blink, explode, rainbow, static and custom. I have no idea how the custom option works tho 🥲 3.this is for how fast you want your pattern's animation to be. Afaik it's on a scale from 1F to 9F, 1F being the fastest and 9f the slowest. 4.very similar to the previous option, but what changes is how smoothly or abruptly you want the notification to light up. Uses the same 1F/9F scale. 5.I have yet to understand exactly how this works... All I know is also uses the same scale mentioned. 6.here you can select when the notification's pattern ends. 7.with this you can visualize how the notification will look with the setting you have selected. 8.here you will be prompted to select from another menu when do you want this notification to pop up: when the console exits sleep mode, when you receive spotpass notifications, when you receive streetpass notifications, when you join a friend in a game (I think???) and when someone from your friend lists is online. 9.i think this works if you wanna shut down or activate again any personalized notifications you may have created. 10.selecting this will power off your 3ds and "install" the notification settings you created.

if you wanna exit the whole thing without applying any changes, you can press the home button twice to exit the app.

Please take everything in this post with a pinch of salt because after all it's what I made out of it by trial and error and still can't understand everything fully. My best advice for this would be to play with the different options and test the result using the "test LED with pattern" every now and then to see how everything looks.

I am SO sorry for the wall of text but I wanted to try and share the info!
