Horizontal divider in Actions List?

Hi Folks,

my searches had no results on this topic, so i try it here:

When the actions list of a character becomes crowded, with spells for example, i whish there where a divider below each entry. Is there any way to add such a thing, maybe to a FG-Theme, or are there already available themes which have such dividers?

What i mean, something like this:

Spellname | Group
Short description
Effects-Action
<------------------------------------>
Spellname | Group
Short description
Effects-Action
<------------------------------------>

No, you have to put them in different groups.
Spells do this by level, not sure if it would mess spells up to have groups "Level 1A" "Level 1B"
