Too many saved layers to display in the UI

I recently created a series of DEM Shading layers to be applied to any map
based on the backcountry avalance forecast (see attached). Ideally, you'd
have a printable map of the terrain with color coded zones reflecting the
relative risk of aspect and elevation. These maps could be created by a
user each day or posted on a website for the major BC skiing zones like CO,
the Sierras, the Wasatch, etc.

I created 120 layers. For each of 8 aspects--N, NE, E, SE, S, SW, W, NW
(defined by degrees)--there are 5 avvy ratings (low, moderate,
considerable, high, and extreme), and 3 elevations (1: >11,500' [above
treeline]; 2: 11,250' to 11,500 [around treeline]; 3: <11,250' [below
treeline], which I roughly based on the Berthoud Pass area of Colorado).
The idea was to toggle/overlay the appropriate layer based on the forecast.
For example, if the forecast rates N and E aspects above treeline as
considerable and as moderate around treeline, I could toggle the
appropriate layers (my naming convention): N1 cons, E1 cons, N2 mod, E2
mod. This forecast is unrealistic but it uses the layers I can access. see

*My main problem* is that the active layers drop down in the UI can't fit
all 120 of the saved custom layers and there is no slider to scroll down to
the ones that won't fit on the screen. The layers are saved to my account,
but I don't know how to access and activate the ones that are now visible
in the UI.

Do you have a solution for this?

Also, I'd like to add some graphic overlay for the type of danger
associated with each layer. For example, if the "wind slab" danger is
considerable and the persistent slab layer moderate, I'd like to
distinguish those types of danger and, at least, represent the highest
danger in a given aspect and elevation.

Any thoughts on that would be great as well.

I understand that my descriptions may not be entirely clear. Please, if you
have questions about what I am trying to do or suggestions please reach out
for clarification.

Lastly, I am not entirely happy with the colors I chose. I was trying to
make subtle distinctions between different aspect while maintaining a theme
for each level of risk. IOW, low-risk is a slightly different shade of blue
for each aspect at each of the 3 elevations (8 aspects and 3 elevations).

Any thoughts on that would be appreciated as well.
