Other than bad UX, no

Describe the solution you'd like
I am learning about WLED, and as I go through it I noticed tat every time the board lost power, the LED settings that I had revert to the default (a solid orange color). It took a while to track down how to get this to boot to my preferences - I read issues from the past that specified that you needed to compile your own version that has a user save mod, etc. Turns out you need to do the following:

1. Save a preset
2. Note the ID of the preset
3. Go to Settings > LED Preferences
4. Apply preset at boot

As a newer user, I assumed it would save whatever I had active - it never occurred to me to create a preset. I think there can be a few different things that could be implemented to improve the UX with this:

• Be able to set a preset to the "boot" preset right from the preset section.
  • Avoids having to go dig for it in the options.
• A notice or banner at the top, explaining that changes will not persist through a powercycle
  • Could also link to a wiki page that explains this

Additional context

I would be interested in possibly tackling something like this. I would need some guidance on how best to implement this. My specialty lies in web frameworks and C# backends. Not sure how the web pages are constructed here.
