Hey there! I wanted to make this suggestion for a while, but wasn't sure if it would get much attention, but here we go anyway!

The main reason I want more themes is because currently, Night Theme is the only theme that I like, because Day and Desert are too bright for me. But many people, including myself, like to have different themes between main and side account to easily tell them apart. But, my side account has Desert theme and it's one of the reasons I barely go on it and mainly use it for extra event currency. The bright colours are a bit of an eyesore for me (especially during the night time).

Currently, there are three available Layout Themes for Lioden: Day, Night, and Desert.
Ever since Desert theme came out, I was wondering if more themes would gradually come out with more natural, well, themes. However, it has been a while, and nothing so far!

I think there are some gorgeous opportunities for themes that could be implemented, for both darker and brighter colour schemes! The few Ideas I have are:

Jungle Theme
Marshlands Theme
Cloud Forest Theme
Mountains Theme
Water Hole Theme
Rocky Shore Theme
Sandy Beach Theme

Let me know what you think, and feel free to suggest more themes that could be implemented! Thanks for reading <3
