I know about that option, but what i mean is possible to change in the main.xml and add some new line introducing some new type of fonts, at the desire location, let say, tracklist header or display on main bar.
Like this example:
<PLAYERBAR>
<Data AllowEnlargeForFont="0" />
<Entry Name="Display" Bitmap="Playerbar_Display.png" NumberImages="1" Margins="5,2,5,2" DrawMode="REGION_E_HSTRETCH,REGION_E_VSTRETCH" >
<DisplayFont TitleSize="100" TitleWeight="100" Status Size="90" StatusWeight="100" /> <Colors TitleText="ffffff" StatusText="ffffff" />
The bolded line is what you can shrink the text on the main toolbar.
I don't know if that is possible because i don't know much about working with commands in the main.xml, only what i can reproduce and copy from other skins. (poor skill on that side
)
