-- The obvious but easily overlooked one because the previews always show the same one: change your page set up.

-- display tags as multilevel (and using them in the first place!) both in module and tags page.

-- using simple CSS to change something in your whole style with !important. For example: a { text-decoration: underline !important; }

-- new options: adding hover text on links list, editing module headings and displaying content in reverse-chronological order on archive pages.

-- using HTML in the custom text module to add images, links, etc.

-- oh one more: displaying the calendar horizontally (works much better in one-column modes)
