Hi, as background, I'm using Lubuntu 13.04. I have gedit 3.6 and I recently installed a markdown plugin from here: gedit-markdown: support for Markdown language in gedit. It works very nicely but I have would like to know if there's any way to customize the plugin's panel. I've attached an image to show that my "regular" gedit window is the way I like it with a slightly tweaked cobalt.xml as the style. My issue is that the lower panel has a white background which I'd like to make "less" white, like #999 or so. I looked at ~/.local/share/gedit/plugins/markdown-preview/__init__.py and org.gnome.gedit.plugins for clues but didn't find any. I should also mention that I've modified my ~/.themes/gtk.css to minimize white wherever possible and that other gtk3 apps apply these mods. /* default color scheme */ Code: /* default color scheme */ @define-color bg_color #9e9e9e; @define-color fg_color #000043; @define-color base_color #8e8e8e; @define-color text_color #000; @define-color selected_bg_color #091825; @define-color selected_fg_color #a2e5fb; @define-color tooltip_bg_color #333333; @define-color tooltip_fg_color #aaaaaa; I'm not proficient at coding but I don't mind editing text (.css, .html, .py) files if a solution lies that way.
