Proxima has made a number of tiles in various colours which are intended to match one of the original styles:

Amiga blue, which I'd suggest be added to all of them

A slightly cooler shade of blue, intended for use with orig_crystal

Brown, intended for use with orig_dirt, orig_pillar

Indigo, intended for use with orig_marble

Olive, intended for use with orig_pillar, ohno_rock

Purple, intended for use with orig_marble, ohno_bubble, ohno_rock

Red, intended for use with orig_fire, ohno_brick
I'd like to suggest that we go ahead and add these to the original styles as background images. It's KB of difference in file size for easy access to these style-enhancing background colours. Note that adding these will not change the theme background colour, it will simply make the background available alongside each of the suggested styles in the Editor.
If there are no objections, this will go ahead in the next update.

Added placeholder Menu graphics & layout to differentiate NeoLemmix "CE" from regular NeoLemmix - Please note: the current updated graphics are placeholders so that CE 1.0 is immediately visually different from NL 12.14. A topic will be made for updating the main menu in due course, where we can discuss gfx, layout, etc in more depth, to be applied in a future update.

Sleeper lemming state - this state is entered when time runs out and the lemming reaches the exit. It's a mostly aesthetic state to replace the buggy-looking cluster of exiting lems, but it's also useful for simulating exit behaviour as these lems cannot be assigned to, and are deducted from the lemming count
) to the topics I think might be somewhat controversial at this early stage, and will give extra time for feedback before adding these. And of course, anything without the Clamoji is also still open for discussion and feedback.
