Theme Folder Structure
For a theme to function as intended, you will need to use the proper folder structure containing all your files in the correct place. Below is an example of the correct structure that you can replicate if you are creating/editing a theme.
.
├── credits.txt
├── font
│ └── default.bin
│ ├── header
| │ └── default.bin
│ ├── footer
| │ └── default.bin
│ ├── panel
| │ └── default.bin
├── glyph
│ ├── muxlaunch
│ | ├── explore.png
│ | ├── favourite.png
│ | ├── history.png

│ | ├── config.png
│ | ├── reboot.png
│ | ├── shutdown.png

│ └── muxtester.txt
├── music
└── sound
In the above example, there are some files here that are not necessary to have a working theme - however the elements included above show off the amount of possible customisation available.
- font - Here is where you can place custom fonts compiled into a
.bin
format. Fonts placed in the panel subfolder will override the font used for list items. Fonts placed in the header subfolder will override the font used for the header. Fonts placed in the footer subfolder will override the font used for the footer. - glyph - Place png images for list item glyphs. See Theme Folder Structure Glyphs section for full list of names.
- image - Place all image assets of your theme here. Animated images are also supported (use
.gif
).- static - Images can be set to sit on top of other elements. They are named following their associated program.
- wall - All backgrounds used sit here. Anything named
default.xxx
is applied on all programs without dedicated assets.
- scheme - The brain of the theme. This file will tell your device how windows and text should appear per program, and will also tell your device how to use the files you have dropped into your image folder.
- music + sound - These folders will contain files heard during your time in the muOS menus. Yet to be implemented.
Theme Folder Structure Glyphs
The following images are used for populating the glyphs displayed in the headers, footers, and list items.
Note: If your theme does not supply images for the glyphs below then it will fall back to built in default images. If you want to hide glyphs you will need to adjust the appropriate settings in your scheme file. For example disable list item glyphs you would set these settings in your scheme file:
[list]
LIST_DEFAULT_GLYPH_ALPHA=0
LIST_FOCUS_GLYPH_ALPHA=0

Program Names
muOS has numerous programs, so they are individually named so that you Themers can set different properties for every single page if you so wish to do so! Anything named default.xxx
in the above folder structure can be renamed to mux...
to apply ideas to single pages.
You can also set images to appear for individual list items (see the files above under ./image/static/muxlaunch/
.
Caution - as muOS is a constantly updating system, there is a high chance that in time, list items will be added or removed from sections. Be wary of this when creating graphics that show all the options for a program.
Check out the updated naming conventions of all muxprograms below;
