Ok, so now I've created my first skin, which does some things better already for me than existing skins. But now come the more detailed refinements. I have a couple of custom tags in my audio files, like instrument types, date of composition or first performance, comment etc., which I rely on a lot in the desktop version of foobar2000. For the mobile version I tried something like this:

[label]
108,2950,2450,100
left
[rgb-135-135-135][comment]

But all it does is display "[comment]", but not the content of the tag. Is there any way to display custom tags at all?
