Problems solved: Colors are showing up where they're supposed to be, property names are updated, layers are merged together better.

Problems not solved: Images aren't showing up where they're supposed to be, text still isn't being overridden on presentation group. (Sob, I'm afraid I wasn't really sure what you meant I should do about the presentation group, so... I tried!)

abstractia.pm:

Prop group presentation:
propgroup presentation { property use num_items_recent; property use num_items_reading; property use use_journalstyle_entry_page; property use layout_type; property use tags_page_type; property string sidebar_width { des = "Set the width of a single sidebar. (Enter JUST '20' for 20%.)"; example = "20"; } property string margins_size { des = "Size of left and right margins. (Enter JUST '5' for 5%.)"; size = 5; } property use sidebar_width; property use margins_size; property string entry_poster_alignment { des = "Alignment of entry poster"; values = "none|None (don't show)|left|Left|right|Right"; } property string entry_poster_position { des = "Position of entry poster"; values = "header|Header|top|Top of entry|bottom|Bottom of entry|footer|Footer"; } property use entry_poster_alignment; property use entry_poster_position; property use userpics_style_group; property use userpics_position; property use entry_metadata_position; property use use_custom_friend_colors; property use use_shared_pic; property use userlite_interaction_links; property use entry_management_links; property use comment_management_links; property use entry_datetime_format_group; property use comment_datetime_format_group; } set sidebar_width = "20"; set margins_size = "5"; set layout_type = "two-columns-right"; set userpics_position = "right"; set entry_poster_alignment = "right"; set entry_poster_position = "header"; set use_custom_friend_colors = false; set custom_foreground_element = "userpic_border"; set custom_background_element = "userpic_background";

Is it the property use things that're getting in my way? Where should I put my override definitions, if not in here?
