Alt-mode texture/icon

[Lime]

Is there a way to set the texture/icon for an entity to be shown in alt-mode?
For example, I'd like to have a possibility to mod an entity that would have different textures based on the status of alt-mode: one for "on" and one for "off".

Or a RenderLayer that is shown/hidden based on alt-mode status.

Set the only_in_alt_mode = true

I see... are there any libraries or examples how to properly implement UIs?

@moderator can you, please, move this topic to suggestions forum? Basically:
- implement a render layer that is visible in alt-mode only, or
- implement few render layers that can be toggled by a hotkey, not limited to alt only
