Pocketbook Era Themes

Hi everyone,

I just received my PocketBook Era today and so far, I'm really enjoying it! I have installed KOReader and everything looks great.

I saw some talks on this fourm that are pretty dated about PocketBook themes. I took a look at them and downloaded some of the files attached to those posts but I can't seem to figure out who to edit the Lines.pbt file.

Does anyone know how themes still work and if I can even edit them still?

Thanks :)
